Image Filtering Functions

Linear and non-linear image filtering functions.

Filtering functions are classified as Neighborhood Operations. It is the user’s responsibility to avoid Sampling Beyond Image Boundaries .

These functions can be found in the nppif library. Linking to only the sub-libraries that you use can significantly save link time, application load time, and CUDA runtime startup time when using dynamic libraries.

Image 1D Linear Filters

1DLinearFilter

The set of 1D linear filtering functions available in the library.

Image Filter Column

FilterColumn

Apply convolution filter with user specified 1D column of weights.

Common parameters for nppiFilterColumn functions:

Result pixel is equal to the sum of the products between the kernel coefficients (pKernel array) and corresponding neighboring column pixel values in the source image defined by nKernelDim and nAnchorY, divided by nDivisor.

param pSrc

Source-Image Pointer.

param nSrcStep

Source-Image Line Step.

param pDst

Destination-Image Pointer.

param nDstStep

Destination-Image Line Step.

param oROI

Region-Of-Interest (ROI).

param pKernel

Pointer to the start address of the kernel coefficient array. Coefficients are expected to be stored in reverse order.

param nMaskSize

Length of the linear kernel array.

param nAnchor

Y offset of the kernel origin frame of reference relative to the source pixel.

param nDivisor

The factor by which the convolved summation from the Filter operation should be divided. If equal to the sum of coefficients, this will keep the maximum result value within full scale.

param nppStreamCtx

Application Managed Stream Context.

Image Filter Column Border

FilterColumnBorder

General purpose 1D convolution column filter with border control.

Pixels under the mask are multiplied by the respective weights in the mask and the results are summed. Before writing the result pixel the sum is scaled back via division by nDivisor. If any portion of the mask overlaps the source image boundary the requested border type operation is applied to all mask pixels which fall outside of the source image.

Currently only the NPP_BORDER_REPLICATE border type operation is supported.

Common parameters for nppiFilterColumnBorder functions:

param pSrc

Source-Image Pointer.

param nSrcStep

Source-Image Line Step.

param oSrcSize

Source image width and height in pixels relative to pSrc.

param oSrcOffset

The pixel offset that pSrc points to relative to the origin of the source image.

param pDst

Destination-Image Pointer.

param nDstStep

Destination-Image Line Step.

param oSizeROI

Region-Of-Interest (ROI).

param pKernel

Pointer to the start address of the kernel coefficient array. Coeffcients are expected to be stored in reverse order.

param nMaskSize

Width of the kernel.

param nAnchor

X offset of the kernel origin frame of reference relative to the source pixel.

param nDivisor

The factor by which the convolved summation from the Filter operation should be divided. If equal to the sum of coefficients, this will keep the maximum result value within full scale.

param eBorderType

The border type operation to be applied at source image border boundaries.

param nppStreamCtx

Application Managed Stream Context.

Image Filter Row Border

FilterRowBorder

General purpose 1D convolution row filter with border control.

Pixels under the mask are multiplied by the respective weights in the mask and the results are summed. Before writing the result pixel the sum is scaled back via division by nDivisor. If any portion of the mask overlaps the source image boundary the requested border type operation is applied to all mask pixels which fall outside of the source image.

Currently only the NPP_BORDER_REPLICATE border type operation is supported.

Common parameters for nppiFilterRowBorder functions:

param pSrc

Source-Image Pointer.

param nSrcStep

Source-Image Line Step.

param oSrcSize

Source image width and height in pixels relative to pSrc.

param oSrcOffset

The pixel offset that pSrc points to relative to the origin of the source image.

param pDst

Destination-Image Pointer.

param nDstStep

Destination-Image Line Step.

param oSizeROI

Region-Of-Interest (ROI).

param pKernel

Pointer to the start address of the kernel coefficient array. Coeffcients are expected to be stored in reverse order.

param nMaskSize

Width of the kernel.

param nAnchor

X offset of the kernel origin frame of reference relative to the source pixel.

param nDivisor

The factor by which the convolved summation from the Filter operation should be divided. If equal to the sum of coefficients, this will keep the maximum result value within full scale.

param eBorderType

The border type operation to be applied at source image border boundaries.

param nppStreamCtx

Image Filter Border

FilterBorder

General purpose 2D convolution filter with border control.

Pixels under the mask are multiplied by the respective weights in the mask and the results are summed. Before writing the result pixel the sum is scaled back via division by nDivisor. If any portion of the mask overlaps the source image boundary the requested border type operation is applied to all mask pixels which fall outside of the source image.

Currently only the NPP_BORDER_REPLICATE border type operation is supported.

Common parameters for nppiFilterBorder functions:

param pSrc

Source-Image Pointer.

param nSrcStep

Source-Image Line Step.

param oSrcSize

Source image width and height in pixels relative to pSrc.

param oSrcOffset

The pixel offset that pSrc points to relative to the origin of the source image.

param pDst

Destination-Image Pointer.

param nDstStep

Destination-Image Line Step.

param oSizeROI

Region-Of-Interest (ROI).

param pKernel

Pointer to the start address of the kernel coefficient array. Coeffcients are expected to be stored in reverse order.

param oKernelSize

Width and Height of the rectangular kernel.

param oAnchor

X and Y offsets of the kernel origin frame of reference relative to the source pixel.

param nDivisor

The factor by which the convolved summation from the Filter operation should be divided. If equal to the sum of coefficients, this will keep the maximum result value within full scale.

param eBorderType

The border type operation to be applied at source image border boundaries.

param nppStreamCtx

Application Managed Stream Context.

Image Filter Min Border

FilterMinBorder

Result pixel value is the minimum of pixel values under the rectangular mask region with border control.

If any portion of the mask overlaps the source image boundary the requested border type operation is applied to all mask pixels which fall outside of the source image.

Currently only the NPP_BORDER_REPLICATE border type operation is supported.

Common parameters for nppiFilterMinBorder functions:

param pSrc

Source-Image Pointer.

param nSrcStep

Source-Image Line Step.

param oSrcSize

Fixed Filters

Fixed Filters

Fixed filters perform linear filtering operations (such as convolutions) with predefined kernels of fixed sizes. Note that this section also contains a few dynamic kernel filters, namely GaussAdvanced and Bilateral.

Some of the fixed filters have versions with border control. For these functions, if any portion of the mask overlaps the source image boundary the requested border type operation is applied to all mask pixels which fall outside of the source image.

Currently only the NPP_BORDER_REPLICATE border type operation is supported for these functions.

Image Filter Gauss Border

FilterGaussBorder

Filters the image using a Gaussian filter kernel with border control. Use FilterGaussAdvancedBorder if you want to supply your own filter coefficients.

If any portion of the mask overlaps the source image boundary the requested border type operation is applied to all mask pixels which fall outside of the source image.

Currently only the NPP_BORDER_REPLICATE border type operation is supported.

Note that all FilterGaussBorder functions currently support mask sizes up to 15x15. Filter kernels for these functions are calculated using a sigma value of 0.4F + (mask width / 2) * 0.6F.

Common parameters for nppiFilterGaussBorder functions:

param pSrc

Source-Image Pointer.

param nSrcStep

Source-Image Line Step.

param oSrcSize

Full source image width and height in pixels.

param oSrcOffset

The pixel offset that pSrc points to relative to the origin of the source image.

param pDst

Destination-Image Pointer.

param nDstStep

Destination-Image Line Step.

param oSizeROI

Region-Of-Interest (ROI).

param eMaskSize

Enumeration value specifying the mask size.

param eBorderType

The border type operation to be applied at source image border boundaries.

param nppStreamCtx

Application Managed Stream Context.

Image Filter Advanced Gauss Border

FilterGaussAdvancedBorder

Filters the image using a separable Gaussian filter kernel with user supplied floating point coefficients with border control.

If any portion of the mask overlaps the source image boundary the requested border type operation is applied to all mask pixels which fall outside of the source image.

Note that the performance of these functions can drop significantly for filter kernels with a very large number of taps.

Currently only the NPP_BORDER_REPLICATE and NPP_BORDER_MIRROR border type operations are supported.

Common parameters for nppiFilterGaussAdvancedBorder functions:

param pSrc

Source-Image Pointer.

param nSrcStep

Source-Image Line Step.

param oSrcSize

Full source image width and height in pixels.

param oSrcOffset

The pixel offset that pSrc points to relative to the origin of the source image.

param pDst

Destination-Image Pointer.

param nDstStep

Destination-Image Line Step.

param oSizeROI

Region-Of-Interest (ROI).

param nFilterTaps

The number of filter taps where nFilterTaps = 2 * ((int)((float)ceil(radius) + 0.5F) ) + 1.

param pKernel

Pointer to an array of nFilterTaps kernel coefficients which sum to 1.0F.

param eBorderType

The border type operation to be applied at source image border boundaries.

param nppStreamCtx

Application Managed Stream Context.

Image Filter Bilateral Gauss Border

FilterBilateralGaussBorder

Filters the image using a bilateral Gaussian filter kernel with border control.

If any portion of the mask overlaps the source image boundary the requested border type operation is applied to all mask pixels which fall outside of the source image.

For this filter the anchor point is always the central element of the kernel. Coefficients of the bilateral filter kernel depend on their position in the kernel and on the value of some source image pixels overlayed by the filter kernel. Only source image pixels with both coordinates divisible by nDistanceBetweenSrcPixels are used in calculations.

The value of an output pixel \(d\) is

\[d = \frac{\sum_{h=-nRadius}^{nRadius}\sum_{w=-nRadius}^{nRadius}W1(h,w)\cdot W2(h,w)\cdot S(h,w)}{\sum_{h=-nRadius}^{nRadius}\sum_{w=-nRadius}^{nRadius}W1(h,w)\cdot W2(h,w)}\]

where h and w are the corresponding kernel width and height indexes, S(h,w) is the value of the source image pixel overlayed by filter kernel position (h,w), W1(h,w) is func(nValSquareSigma, (S(h,w) - S(0,0))) where S(0,0) is the value of the source image pixel at the center of the kernel, W2(h,w) is func(nPosSquareSigma, sqrt(h*h+w*w)), and func is the following formula

\[func(S,I) = exp(-\frac{I^2}{2.0F\cdot S^2})\]

Currently only the NPP_BORDER_REPLICATE border type operations are supported.

Common parameters for nppiFilterBilateralGaussBorder functions:

param pSrc

Source-Image Pointer.

param nSrcStep

Source-Image Line Step.

param oSrcSize

Source image width and height in pixels relative to pSrc.

param oSrcOffset

The pixel offset that pSrc points to relative to the origin of the source image.

param pDst

Destination-Image Pointer.

param nDstStep

Destination-Image Line Step.

param oSizeROI

Region-Of-Interest (ROI).

param nRadius

The radius of the round filter kernel to be used. A radius of 1 indicates a filter kernel size of 3 by 3, 2 indicates 5 by 5, etc. Radius values from 1 to 32 are supported.

param nStepBetweenSrcPixels

The step size between adjacent source image pixels processed by the filter kernel, most commonly 1.

param nValSquareSigma

The square of the sigma for the relative intensity distance between a source image pixel in the filter kernel and the source image pixel at the center of the filter kernel.

param nPosSquareSigma

The square of the sigma for the relative geometric distance between a source image pixel in the filter kernel and the source image pixel at the center of the filter kernel.

param eBorderType

The border type operation to be applied at source image border boundaries.

param nppStreamCtx

Application Managed Stream Context.

Image Filter High Pass Border

FilterHighPassBorder

Filters the image using a high-pass filter kernel with border control.

If any portion of the mask overlaps the source image boundary the requested border type operation is applied to all mask pixels which fall outside of the source image.

Currently only the NPP_BORDER_REPLICATE border type operation is supported.

Common parameters for nppiFilterHighPassBorder functions:

\[\begin{split} \left( \begin{array}{rrr} -1 & -1 & -1 \\ -1 & 8 & -1 \\ -1 & -1 & -1 \\ \end{array} \right) \left( \begin{array}{rrrrr} -1 & -1 & -1 & -1 & -1 \\ -1 & -1 & -1 & -1 & -1 \\ -1 & -1 & 24 & -1 & -1 \\ -1 & -1 & -1 & -1 & -1 \\ -1 & -1 & -1 & -1 & -1 \\ \end{array} \right) \end{split}\]

Image Filter Unsharp Border

FilterUnsharpBorder

Filters the image using a unsharp-mask sharpening filter kernel with border control.

The algorithm involves the following steps: Smooth the original image with a Gaussian filter, with the width controlled by the nRadius. Subtract the smoothed image from the original to create a high-pass filtered image. Apply any clipping needed on the high-pass image, as controlled by the nThreshold. Add a certain percentage of the high-pass filtered image to the original image, with the percentage controlled by the nWeight. In pseudocode this algorithm can be written as: HighPass = Image - Gaussian(Image) Result = Image + nWeight * HighPass * ( |HighPass| >= nThreshold ) where nWeight is the amount, nThreshold is the threshold, and >= indicates a Boolean operation, 1 if true, or 0 otherwise.

If any portion of the mask overlaps the source image boundary, the requested border type operation is applied to all mask pixels which fall outside of the source image.

Currently only the NPP_BORDER_REPLICATE border type operation is supported.

Image Filter Wiener Border

FilterWienerBorder

Noise removal filtering of an image using an adaptive Wiener filter with border control.

Pixels under the source mask are used to generate statistics about the local neighborhood which are then used to control the amount of adaptive noise filtering locally applied.

Note that if the noise value for a particular channel is set to 0.0f then the output for that channel will contain the square of the variance of local pixels within aMaskSize surrounding each pixel in oSizeROI. Note that is unlikely to be useful unless the pixel data type is floating point due to result clamping. Output from these cases can then be passed through an nppiMean function call using the same oSizeROI. The square root for that channel from the nppiMean call result can then be used as a noise value for a future call to this function if there is no known preexisting noise value.

Currently only the NPP_BORDER_REPLICATE border type operation is supported.

Common parameters for nppiFilterWienerBorder functions:

For each pixel in the source image the function estimates the local mean and variance in the neighborhood defined by oMaskSize relative to the primary source pixel located at oAnchor.x and oAnchor.y. Given an oMaskSize with width \(W\) and height \(H\), the mean, variance, and destination pixel value will be computed per channel as

\[Mean = \frac{1}{W\cdot H}\sum_{j=0}^{H-1}\sum_{i=0}^{W-1}pSrc(j,i)\]

\[Variance^2 = \frac{1}{W\cdot H}\sum_{j=0}^{H-1}\sum_{i=0}^{W-1}(pSrc(j,i)^2-Mean^2)\]

\[pDst(j,i) = Mean+\frac{(Variance^2-NoiseVariance^2)}{Variance^2}\cdot {(pSrc(j,i)-Mean)}\]

Image Filter Gradient Vector Prewitt Border

GradientVectorPrewittBorder

RGB Color to Prewitt Gradient Vector conversion using user selected fixed mask size and gradient distance method. Functions support up to 4 optional single channel output gradient vectors, X (vertical), Y (horizontal), magnitude, and angle with user selectable distance methods. Output for a particular vector is disabled by supplying a NULL pointer for that vector. X and Y gradient vectors are in cartesian form in the destination data type.

Magnitude vectors are polar gradient form in the destination data type, angle is always in floating point polar gradient format. Only fixed mask sizes of 3x3 are supported. Only nppiNormL1 (sum) and nppiNormL2 (sqrt of sum of squares) distance methods are currently supported.

Currently only the NPP_BORDER_REPLICATE border type operation is supported. Borderless output can be accomplished by using a larger source image than the destination and adjusting oSrcSize and oSrcOffset parameters accordingly.

Common parameters for nppiFilterGradientVectorPrewittBorder functions:

The following fixed kernel mask is used for producing the pDstX (vertical) output image.

\[\begin{split} \left( \begin{array}{rrr} -1 & 0 & 1 \\ -1 & 0 & 1 \\ -1 & 0 & 1 \\ \end{array} \right) \end{split}\]

The following fixed kernel mask is used for producing the pDstY (horizontal) output image.

\[\begin{split} \left( \begin{array}{rrr} 1 & 1 & 1 \\ 0 & 0 & 0 \\ -1 & -1 & -1 \\ \end{array} \right) \end{split}\]

For the C1R versions of the function the pDstMag output image value for L1 normalization consists of the absolute value of the pDstX value plus the absolute value of the pDstY value at that particular image pixel location. For the C1R versions of the function the pDstMag output image value for L2 normalization consists of the square root of the pDstX value squared plus the pDstY value squared at that particular image pixel location. For the C1R versions of the function the pDstAngle output image value consists of the arctangent (atan2) of the pDstY value and the pDstX value at that particular image pixel location.

For the C3C1R versions of the function, regardless of the selected normalization method, the L2 normalization value is first determined for each or the pDstX and pDstY values for each source channel then the largest L2 normalization value (largest gradient) is used to select which of the 3 pDstX channel values are output to the pDstX image or pDstY channel values are output to the pDstY image. For the C3C1R versions of the function the pDstMag output image value for L1 normalizaton consists of the same technique used for the C1R version for each source image channel. Then the largest L2 normalization value is again used to select which of the 3 pDstMag channel values to output to the pDstMag image. For the C3C1R versions of the function the pDstMag output image value for L2 normalizaton consists of just outputting the largest per source channel L2 normalization value to the pDstMag image. For the C3C1R versions of the function the pDstAngle output image value consists of the same technique used for the C1R version calculated for each source image channel. Then the largest L2 normalization value is again used to select which of the 3 angle values to output to the pDstAngle image.

Image Filter Gradient Vector Scharr Border

GradientVectorScharrBorder

RGB Color to Scharr Gradient Vector conversion using user selected fixed mask size and gradient distance method. Functions support up to 4 optional single channel output gradient vectors, X (vertical), Y (horizontal), magnitude, and angle with user selectable distance methods. Output for a particular vector is disabled by supplying a NULL pointer for that vector. X and Y gradient vectors are in cartesian form in the destination data type.

Magnitude vectors are polar gradient form in the destination data type, angle is always in floating point polar gradient format. Only fixed mask sizes of 3x3 are supported. Only nppiNormL1 (sum) and nppiNormL2 (sqrt of sum of squares) distance methods are currently supported.

Currently only the NPP_BORDER_REPLICATE border type operation is supported. Borderless output can be accomplished by using a larger source image than the destination and adjusting oSrcSize and oSrcOffset parameters accordingly.

Common parameters for nppiFilterGradientVectorScharrBorder functions:

The following fixed kernel mask is used for producing the pDstX (vertical) output image.

\[\begin{split} \left( \begin{array}{rrr} 3 & 0 & -3 \\ 10 & 0 & -10 \\ 3 & 0 & -3 \\ \end{array} \right) \end{split}\]

The following fixed kernel mask is used for producing the pDstY (horizontal) output image.

\[\begin{split} \left( \begin{array}{rrr} 3 & 10 & 3 \\ 0 & 0 & 0 \\ -3 & -10 & -3 \\ \end{array} \right) \end{split}\]

For the C1R versions of the function the pDstMag output image value for L1 normalization consists of the absolute value of the pDstX value plus the absolute value of the pDstY value at that particular image pixel location. For the C1R versions of the function the pDstMag output image value for L2 normalization consists of the square root of the pDstX value squared plus the pDstY value squared at that particular image pixel location. For the C1R versions of the function the pDstAngle output image value consists of the arctangent (atan2) of the pDstY value and the pDstX value at that particular image pixel location.

For the C3C1R versions of the function, regardless of the selected normalization method, the L2 normalization value is first determined for each or the pDstX and pDstY values for each source channel then the largest L2 normalization value (largest gradient) is used to select which of the 3 pDstX channel values are output to the pDstX image or pDstY channel values are output to the pDstY image. For the C3C1R versions of the function the pDstMag output image value for L1 normalizaton consists of the same technique used for the C1R version for each source image channel. Then the largest L2 normalization value is again used to select which of the 3 pDstMag channel values to output to the pDstMag image. For the C3C1R versions of the function the pDstMag output image value for L2 normalizaton consists of just outputting the largest per source channel L2 normalization value to the pDstMag image. For the C3C1R versions of the function the pDstAngle output image value consists of the same technique used for the C1R version calculated for each source image channel. Then the largest L2 normalization value is again used to select which of the 3 angle values to output to the pDstAngle image.

Image Filter Distance Transform

FilterDistanceTransform

Performs Exact Euclidean Distance Transform function using the Parallel Banding Algorithm (PBA+) defined by Tiow-Seng Tan, et al paper named “Parallel Banding Algorithm to Compute Exact Distance Transform with the GPU” published dated August 8, 2019.

Output for these functions is an optional 16-bit signed integer voronoi diagram (pairs of signed 16 bit integer x, y distance values) and/or an optional true euclidean distance transform image generated from the internal voronoi diagram in either unsigned 16-bit truncated integer format or 32-bit floating point format. Additional optional output can include an signed 16-bit integer Voronoi diagram containing site indices and/or a signed 16-bit integer Voronoi diagram containing relative Manhattan distances to the closest sites. Minimum and maximum image ROI widths and heights are 64 and 32767.

Note that an input image that does not contain at least one site pixel is considered to be an invalid image. If you suspect that your input image may be invalid you can call an NPP function like nppiCountInRange() first to confirm that the image is valid before calling the distance transform function.

The nMinSiteValue and nMaxSiteValue parameters can be used to control which source image pixels are considered sites(traditionally 0) and non-sites (everything else).

Antialiased true distance transform, when available, is only available as double precision floating point (Npp64f) output data only and is enabled by setting the pAntialiasingDeviceBuffer pointer parameter to a non-NULL value.

The algorithm used for antialising is derived from the edtaa4 version from “Anti-aliased Euclidean distance transform” by Stefan Gustavson et. al. published in 2009 and is used under the permissions specified below.

Derived from edtaa4.c - compute the Euclidean distance transform of an image, with more accurate handling of 1 pixel wide anti-aliased edges.

This is a MEX-file for MATLAB. MATLAB is a product of The MathWorks, Inc.

Code in “edtaa4func.c” originally by Stefan Gustavson 1994, implemented from a verbal description in the PhD dissertation of Ingemar Ragnemalm, dept of EE, Linkoping University.

Image Filter Harris Corners Border

FilterHarrisCornersBorder

Performs Harris Corner detection on a single channel 8-bit grayscale image and outputs a single channel 32-bit floating point image consisting the corner response at each pixel of the image.

The algorithm consists of two phases. The first phase generates the floating point product of XX, YY, and XY gradients at each pixel in the image. The type of gradient used is controlled by the eFilterType and eMaskSize parameters. The second phase averages those products over a window of either 3x3 or 5x5 pixels around the center pixel then generates the Harris corner response at that pixel which is output in the destination image. The Harris response value is determined as H = ((XX * YY - XY * XY) - (nK * ((XX + YY) * (XX + YY)))) * nScale.

Currently only the NPP_BORDER_REPLICATE border type operation is supported. Borderless output can be accomplished by using a larger source image than the destination and adjusting oSrcSize and oSrcOffset parameters accordingly.

Functions

NppStatus nppiFilterHarrisCornersBorderGetBufferSize(NppiSize oSizeROI, int *hpBufferSize)

Calculate scratch buffer size needed for the FilterHarrisCornersBorder function based on destination image SizeROI width and height.

Parameters

• oSizeROI – Region-Of-Interest (ROI).

Image Filter Hough Line

FilterHoughLine

Extracts Hough lines from a single channel 8-bit binarized (0, 255) source feature (canny edges, etc.) image.

Outputs a list of lines in point polar format representing the length (rho) and angle (theta) of each line from the origin of the normal to the line using the formula rho = x cos(theta) + y sin(theta). The level of discretization, nDelta, is specified as an input parameter. The performance and effectiveness of this function highly depends on this parameter with higher performance for larger numbers and more detailed results for lower numbers. Also, lines are not guaranteed to be added to the pDeviceLines list in the same order from one call to the next. However, all of the same lines will still be generated as long as nMaxLineCount is set large enough so that they all can fit in the list. To convert lines in point polar format back to cartesian lines use the following formula:

Npp32f nHough = ((sqrt(2.0F) * static_cast<Npp32f>(oSizeROI.height > oSizeROI.width ? oSizeROI.height 
                                                                                    : oSizeROI.width)) / 2.0F); 
int nAccumulatorsHeight = nDelta.rho > 1.0F ? static_cast<int>(ceil(nHough * 2.0F)) 
                                            : static_cast<int>(ceil((nHough * 2.0F) / nDelta.rho));
int nCenterX = oSizeROI.width >> 1;
int nCenterY = oSizeROI.height >> 1;
Npp32f nThetaRad = static_cast<Npp32f>(deviceline.theta) * 0.0174532925199433F;
Npp32f nSinTheta = sin(nThetaRad);
Npp32f nCosTheta = cos(nThetaRad);
int nX1, nY1, nX2, nY2;

if (deviceline.theta >= 45 && deviceline.theta <= 135) // degrees
{
    // y = (rho - x cos(theta)) / sin(theta)
    nX1 = minimum cartesian X boundary value;
    nY1 = static_cast<int>((static_cast<Npp32f>(deviceline.rho - (nAccumulatorsHeight >> 1)) - 
                           ((nX1 - nCenterX) * nCosTheta)) / nSinTheta + nCenterY);
    nX2 = maximum cartesian X boundary value;
    nY2 = static_cast<int>((static_cast<Npp32f>(deviceline.rho - (nAccumulatorsHeight >> 1)) - 
                           ((nX2 - nCenterX) * nCosTheta)) / nSinTheta + nCenterY);
}

{
    // x = (rho - y sin(theta)) / cos(theta)

The performance and effectiveness of this function highly depends on this parameter with higher performance for larger numbers and more detailed results for lower numbers. nDelta must have the same values as those used in the nppiFilterHoughLineGetBufferSize() function call. The oDstROI region limits are used to limit accepted lines to those that fall within those limits.

Parameters

• pSrc – Source-Image Pointer.

• nSrcStep – Source-Image Line Step.

• oSizeROI – Region-Of-Interest (ROI).

• nDelta – Discretization steps, range 0.0F < radial increment nDelta.rho < 3.0F, 1.0F recommended, range 0.25F < angular increment nDelta.theta < 3.0F, 1.0F recommended.

• nThreshold – Minimum number of points to accept a line.

• pDeviceLines – Device pointer to (nMaxLineCount * sizeof(NppPointPolar) line objects.

• oDstROI – Region limits with oDstROI[0].rho <= accepted rho <= oDstROI[1].rho and oDstROI[0].theta <= accepted theta <= oDstROI[1].theta.

• nMaxLineCount – The maximum number of lines to output.

• pDeviceLineCount – The number of lines detected by this function up to nMaxLineCount.

• pDeviceBuffer – pointer to scratch DEVICE memory buffer of size hpBufferSize (see nppiFilterHoughLineGetBufferSize() above)

Image Filter Histogram Of Oriented Gradients Border

HistogramOfOrientedGradientsBorder

Performs Histogram Of Oriented Gradients operation on source image generating separate windows of Histogram Descriptors for each requested location.

This function implements the simplest form of functionality described by N. Dalal and B. Triggs. Histograms of Oriented Gradients for Human Detection. INRIA, 2005. It supports overlapped contrast normalized block histogram output with L2 normalization only, no threshold clipping, and no pre or post gaussian smoothing of input images or histogram output values. It supports both single channel grayscale source images and three channel color images. For color images, the color channel with the highest magnitude value is used as that pixel’s magnitude. Output is row order only. Descriptors are output consecutively with no separation padding if multiple descriptor output is requested (one desriptor per source image location). For example, common HOG parameters are 9 histogram bins per 8 by 8 pixel cell, 2 by 2 cells per block, with a descriptor window size of 64 horizontal by 128 vertical pixels yielding 7 by 15 overlapping blocks (1 cell overlap in both horizontal and vertical directions). This results in 9 bins * 4 cells * 7 horizontal overlapping blocks * 15 vertical overlapping blocks or 3780 32-bit floating point output values (bins) per descriptor window.

The number of horizontal overlapping block histogram bins per descriptor window width is determined by (((oHOGConfig.detectionWindowSize.width / oHOGConfig.histogramBlockSize) * 2) - 1) * oHOGConfig.nHistogramBins. The number of vertical overlapping block histograms per descriptor window height is determined by (((oHOGConfig.detectionWindowSize.height / oHOGConfig.histogramBlockSize) * 2) - 1) The offset of each descriptor window in the descriptors output buffer is therefore horizontal histogram bins per descriptor window width * vertical histograms per descriptor window height 32-bit floating point values relative to the previous descriptor window output.

The algorithm uses a 1D centered derivative mask of [-1, 0, +1] when generating input magnitude and angle gradients. Magnitudes are added to the two nearest histogram bins of oriented gradients between 0 and 180 degrees using a weighted linear interpolation of each magnitude value across the 2 nearest angular bin orientations. 2D overlapping blocks of histogram bins consisting of the bins from 2D arrangements of cells are then contrast normalized using L2 normalization and output to the corresponding histogram descriptor window for that particular window location in the window locations list.

Some restrictions include:

#define NPP_HOG_MAX_CELL_SIZE                          (16)
#define NPP_HOG_MAX_BLOCK_SIZE                         (64)

#define NPP_HOG_MAX_OVERLAPPING_BLOCKS_PER_DESCRIPTOR (256)
#define NPP_HOG_MAX_DESCRIPTOR_LOCATIONS_PER_CALL     (128)

Currently only the NPP_BORDER_REPLICATE border type operation is supported.

Image Filter Flood Fill

FloodFill

Flood fill a connected region of an image with a specified new value.

FloodFillGetBufferSize

Before calling any of the FloodFill functions the application first needs to call the FloodFillGetBufferSize function to determine the amount of device memory to allocate as a working buffer.

The application allocated device memory is then passed as the pBuffer parameter to the corresponding FloodFill function.

NppStatus nppiFloodFillGetBufferSize(NppiSize oSizeROI, int *hpBufferSize)

Calculate scratch buffer size needed for the FloodFill function based on destination image oSizeROI width and height.

Parameters

• oSizeROI – Region-Of-Interest (ROI).

• hpBufferSize – Required buffer size in bytes.

Flood Fill

FloodFill

In place flood fill of a region of pixels connected to the pixel at the seed pixel location in an image with a new pixel value.

Before calling any of the FloodFill functions the application first needs to call the FloodFillGetBufferSize function to determine the amount of device memory to allocate as a working buffer. The allocated device memory is then passed as the pBuffer parameter to the corresponding FloodFill function.

Optionally the function can return connected region information for the filled region in the pConnectedRegion NppiConnectedRegion structure in host memory. The oBoundingBox x and y will be set to the left and top coordinates and width and height will be set to the right bottom coordinates of the bounding box relative to pSrcDst. Set pConnectedRegion to NULL if not required. Requesting pConnectedRegion information may slightly degrade performance.

Flood Fill Boundary

FloodFillBoundary

In place flood fill of a region of pixels connected to the pixel at the seed pixel location in an image with a new pixel value. Also fill boundary of filled region with a specified color.

Before calling any of the FloodFill functions the application first needs to call the FloodFillGetBufferSize function to determine the amount of device memory to allocate as a working buffer. The allocated device memory is then passed as the pBuffer parameter to the corresponding FloodFill function.

Optionally the function can return connected region information for the filled region in the pConnectedRegion NppiConnectedRegion structure in host memory. The oBoundingBox x and y will be set to the left and top coordinates and width and height will be set to the right bottom coordinates of the bounding box relative to pSrcDst. Set pConnectedRegion to NULL if not required. Requesting pConnectedRegion information may slightly degrade performance.

Flood Fill Range Boundary

FloodFillRangeBoundary

In place flood fill of a region of pixels connected to the pixel at the seed pixel location and with a Pixel value >= Min and <= Max in an image with a new pixel value. Also fill boundary of filled region with a specified color.

Before calling any of the FloodFill functions the application first needs to call the FloodFillGetBufferSize function to determine the amount of device memory to allocate as a working buffer. The allocated device memory is then passed as the pBuffer parameter to the corresponding FloodFill function.

Optionally the function can return connected region information for the filled region in the pConnectedRegion NppiConnectedRegion structure in host memory. The oBoundingBox x and y will be set to the left and top coordinates and width and height will be set to the right bottom coordinates of the bounding box relative to pSrcDst. Set pConnectedRegion to NULL if not required. Requesting pConnectedRegion information may slightly degrade performance.

Flood Fill Gradient Boundary

FloodFillGradientBoundary

In place flood fill of a region of pixels connected to the pixel at the seed pixel location and with an original pixel value including seed - Min to seed + Max in an image with a new pixel value. Also fill boundary of filled region with a specified color.

In place flood fill of a region of pixels connected to the pixel at the seed pixel location in an image with a new pixel value.

Before calling any of the FloodFill functions the application first needs to call the FloodFillGetBufferSize function to determine the amount of device memory to allocate as a working buffer. The allocated device memory is then passed as the pBuffer parameter to the corresponding FloodFill function.

Optionally the function can return connected region information for the filled region in the pConnectedRegion NppiConnectedRegion structure in host memory. The oBoundingBox x and y will be set to the left and top coordinates and width and height will be set to the right bottom coordinates of the bounding box relative to pSrcDst. Set pConnectedRegion to NULL if not required. Requesting pConnectedRegion information may slightly degrade performance.

Label Markers

LabelMarkers

Generate image connected region label markers to be used for later image segmentation.

These functions have been deprecated. Use LabelMarkersUF functions instead.

LabelMarkersUFGetBufferSize

Before calling any of the LabelMarkersUF functions the application first needs to call the LabelMarkersGetBufferSize function to determine the amount of device memory to allocate as a working buffer.

The application allocated device memory is then passed as the pBuffer parameter to the corresponding LabelMarkersUF function.

NppStatus nppiLabelMarkersUFGetBufferSize_32u_C1R(NppiSize oSizeROI, int *hpBufferSize)

Calculate scratch buffer size needed 1 channel 32-bit unsigned integer LabelMarkersUF function based on destination image oSizeROI width and height.

Parameters

• oSizeROI – Region-Of-Interest (ROI).

• hpBufferSize – Required buffer size in bytes.

Label MarkersUF

LabelMarkersUF

Generate image connected region label markers to be used for later image segmentation.

A connected region is any pixel region where all pixels in the region have the same pixel value. Note that marker label IDs generally increase in value from image left to right and top to bottom they are not generated in any particular order and there may be numeric gaps between sequential marker IDs. To limit the number of marker IDs generated the application should pass the image through a threshold filter before calling this funcion. Doing so however does not necessarily limit the maximum marker ID value generated by this function. Note that these functions currently only support image ROI sizes up to 4 gigapixels. Also note that while these functions support destination image pitches that are not exactly equal to oSizeROI.width * sizeof(Npp32u) it can avoid a cudaMemCpyAsync() call to copy the final result from the working buffer to the destination image if the pitch exactly equals oSizeROI.width * sizeof(Npp32u).

Before calling any of the LabelMarkersUF functions the application first needs to call the LabelMarkersUFGetBufferSize to determine the amount of device memory to allocate as a working buffer. The allocated device memory is then passed as the pBuffer parameter to the corresponding LabelMarkersUF function.

The algorithm used in this implementation is based on the one described in “An Optimized Union-Find Algorithm for Connected Components Labeling Using GPUs” by Jun Chen and others.

Note that the destination image in these functions must be allocated with cudaMalloc() and NOT cudaMallocPitch(). Also the pitch of the output image MUST be set to oSizeROI.width * sizeof(Npp32u).

Label MarkersUF Batch

LabelMarkersUFBatch

Generate image connected region label markers to be used for later image segmentation for a batched list of images.

A connected region is any pixel region where all pixels in the region have the same pixel value. Note that marker label IDs generally increase in value from image left to right and top to bottom they are not generated in any particular order and there may be numeric gaps between sequential marker IDs. To limit the number of marker IDs generated the application should pass the image through a threshold filter before calling this funcion. Doing so however does not necessarily limit the maximum marker ID value generated by this function. Note that these functions currently only support image ROI sizes up to 4 gigapixels. Also note that these functions work directly in the destination image so destination pitch MUST be equal to destination ROI.width * sizeof(Npp32u) and even if destination pitch is greater than that the output will be in that format. If this doesn’t work for you use the single image version of these functions or cudaMemCopy2D can be called for each output image to restore the original pitch. Note that all source and destination images in the batch list must contain enough device memory to support the full ROI size. ROIs in descriptor lists are ignored in these functions.

The algorithm used in this implementation is based on the one described in “An Optimized Union-Find Algorithm for Connected Components Labeling Using GPUs” by Jun Chen and others.

Generate an output image containing regions of constant value grayscale defined by watershed segmentation plateau boundaries from a grayscale input image.

Optionally output the corresponding marker labels image.

Before calling any of the SegmentWatershed functions the application first needs to call the corresponding SegmentWatershedGetBufferSize to determine the amount of device memory to allocate as working buffers. The allocatd memory is then passed as the pDeviceMemoryBuffer parameter to the corresponding SegmentWatershed function.

1 channel 8-bit unsigned integer in place image watershed segmentation generation.

Parameters

• pSrcDst – In-Place Image Pointer.

• nSrcDstStep – Source-Image Line Step.

• pMarkerLabels – Device memory pointer to optionally output the corresponding marker labels image, set to NULL if no marker labels image output is desired.

• nMarkerLabelsStep – Marker labels image line step,ignored if pMarkerLabels is NULL.

• eNorm – Type of pixel connectivity test to use, nppiNormInf will use 8 way connectivity and nppiNormL1 will use 4 way connectivity.

• eSegmentBoundaryType – Type of segment boundaries, if any, to be added to output image.

• oSizeROI – Region-Of-Interest (ROI) for both segmented image and corresponding marker labels image.

• pDeviceMemoryBuffer – Pointer to device memory scratch buffer at least as large as value returned by the corresponging SegmentWatershedGetBufferSize call.

• nppStreamCtx – Application Managed Stream Context.
