Image Color Conversion Functions

Routines manipulating an image’s color model and sampling format.

These functions can be found in the nppicc 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.

Here is how NPP converts gamma corrected RGB to CCIR601 Gray.

nGray =  0.299F * R + 0.587F * G + 0.114F * B;

ColorToGray

RGB Color to Gray conversion using user supplied conversion coefficients.

Here is how NPP converts gamma corrected RGB Color to Gray using user supplied conversion coefficients.

nGray =  aCoeffs[0] * R + aCoeffs[1] * G + aCoeffs[2] * B;

For the C4C1R versions of the functions the calculations are as follows.

For BGRA or other formats with alpha just rearrange the coefficients accordingly.

nGray =  aCoeffs[0] * R + aCoeffs[1] * G + aCoeffs[2] * B + aCoeffs[3] * A;

Color Debayer

Grayscale Color Filter Array to RGB Color Debayer conversion.

Generates one RGB color pixel for every grayscale source pixel. Source and destination images must have even width and height. Missing pixel colors are generated using bilinear interpolation with chroma correlation of generated green values (eInterpolation MUST be set to 0). eGrid allows the user to specify the Bayer grid registration position at source image location oSrcROI.x, oSrcROI.y relative to pSrc. Possible registration positions are:

NPPI_BAYER_BGGR  NPPI_BAYER_RGGB  NPPI_BAYER_GBRG  NPPI_BAYER_GRBG

      B G              R G              G B              G R
      G R              G B              R G              B G

If it becomes necessary to access source pixels outside source image then the source image borders are mirrored.

Here is how the algorithm works. R, G, and B base pixels from the source image are used unmodified. To generate R values for those G pixels, the average of R(x - 1, y) and R(x + 1, y) or R(x, y - 1) and R(x, y + 1) is used depending on whether the left and right or top and bottom pixels are R base pixels. To generate B values for those G pixels, the same algorithm is used using nearest B values. For an R base pixel, if there are no B values in the upper, lower, left, or right adjacent pixels then B is the average of B values in the 4 diagonal (G base) pixels. The same algorithm is used using R values to generate the R value of a B base pixel. Chroma correlation is applied to generated G values only, for a B base pixel G(x - 1, y) and G(x + 1, y) are averaged or G(x, y - 1) and G(x, y + 1) are averaged depending on whether the absolute difference between B(x, y) and the average of B(x - 2, y) and B(x + 2, y) is smaller than the absolute difference between B(x, y) and the average of B(x, y - 2) and B(x, y + 2). For an R base pixel the same algorithm is used testing against the surrounding R values at those offsets. If the horizontal and vertical differences are the same at one of those pixels then the average of the four left, right, upper and lower G values is used instead.

ColorTwistBatch

Routines for converting between various image color models using user supplied matrix coefficients on batches of images.

ColorTwistBatch

Perform color twist pixel batch processing.

Color twist consists of applying the following formula to each image pixel using coefficients from one or more user supplied color twist device memory matrix arrays as follows where dst[x] and src[x] represent destination pixel and source pixel channel or plane x. The full sized coefficient matrix should be sent for all pixel channel sizes, the function will process the appropriate coefficients and channels for the corresponding pixel size. ColorTwistBatch generally takes the same parameter list as ColorTwist except that there is a list of N instances of those parameters (N > 1) and that list is passed in device memory; The matrix pointers referenced for each image in the batch also need to point to device memory matrix values. A convenient data structure is provided that allows for easy initialization of the parameter lists. The only restriction on these functions is that there is one single ROI which is applied respectively to each image in the batch. The primary purpose of this function is to provide improved performance for batches of smaller images as long as GPU resources are available. Therefore it is recommended that the function not be used for very large images as there may not be resources available for processing several large images simultaneously. 

dst[0] = aTwist[0][0] * src[0] + aTwist[0][1] * src[1] + aTwist[0][2] * src[2] + aTwist[0][3]

ColorTwistWithModelAndFormatConversion

Routines for converting between various image color models using user supplied matrix coefficients.

RGBToYUVColorTwist

Normally, color twist is a 3-channel operation that takes place on RGB data.

The following functions also perform the color twist operation, but while converting between image formats: RGBToYUV420, RGBToYUV422, and RGBToNV12.

To recap color twist pixel processing: Color twist consists of applying the following formula to each image pixel using coefficients from the user supplied color twist host matrix array as follows where dst[x] and src[x] represent destination pixel and source pixel channel or plane x. The full sized coefficient matrix should be sent for all pixel channel sizes, the function will process the appropriate coefficients and channels for the corresponding pixel size.

This is how the matrix works for a RGB->YUV420/YUV422/NV12 forward transform:

dst[0] = aTwist[0][0] * src[0] + aTwist[0][1] * src[1] + aTwist[0][2] * src[2] + aTwist[0][3]
dst[1] = aTwist[1][0] * src[0] + aTwist[1][1] * src[1] + aTwist[1][2] * src[2] + aTwist[1][3]
dst[2] = aTwist[2][0] * src[0] + aTwist[2][1] * src[1] + aTwist[2][2] * src[2] + aTwist[2][3]

YUVToRGBColorTwist

This is the inverse color twist, a 3-channel operation that takes place on YUV/NV12 data to produce RGB data, supporting the following conversions: YUV420ToRGB, YUV422ToRGB, and NV12ToRGB.

The INVERSE Color twist consists of applying the following formula to each image pixel using coefficients from the user supplied color twist host matrix array as follows where dst[x] and src[x] represent destination pixel and source pixel channel or plane x. The full sized coefficient matrix should be sent for all pixel channel sizes, the function will process the appropriate coefficients and channels for the corresponding pixel size.

This is how the matrix works for the YUV420/YUV/422/NV12->RGB INVERSE transform:

(note- do the offsets first):

src[0]' = src[0] + aTwist[0][3]
src[1]' = src[1] + aTwist[1][3]
src[2]' = src[2] + aTwist[2][3]

And then the remaining 3x3 twist matrix is applied using those modified values:

dst[0] = aTwist[0][0] * src[0]' + aTwist[0][1] * src[1]' + aTwist[0][2] * src[2]'
dst[1] = aTwist[1][0] * src[0]' + aTwist[1][1] * src[1]' + aTwist[1][2] * src[2]'
dst[2] = aTwist[2][0] * src[0]' + aTwist[2][1] * src[1]' + aTwist[2][2] * src[2]'

Since the 4th column of the matrix is the offsets (either 0 or half-max to shift the values to be positive), as they’re applied last in the forward transform (to YUV), they need to be applied FIRST in the inverse transform (back to RGB). This does mean that +-16384 has to be used for 16u images where there was a +-128 for 8u images in both forward and inverse cases.
