Detailed Description

General purpose 2D convolution filter.

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.

Common parameters for nppiFilter functions include:

Parameters
pSrc Source-Image Pointer.
nSrcStep Source-Image Line Step.
pDst Destination-Image Pointer.
nDstStep Destination-Image Line Step.
oSizeROI Region-of-Interest (ROI).
pKernel Pointer to the start address of the kernel coefficient array. Coeffcients are expected to be stored in reverse order.
oKernelSize Width and Height of the rectangular kernel.
oAnchor X and Y offsets of the kernel origin frame of reference relative to the source pixel.
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.
nppStreamCtx Application Managed Stream Context.
Returns
Image Data Related Error Codes, ROI Related Error Codes
