Detailed Description

Compare the pixels of two images and create a binary result image.

In case of multi-channel image types, the condition must be fulfilled for all channels, otherwise the comparison is considered false. The "binary" result image is of type 8u_C1. False is represented by 0, true by NPP_MAX_8U.

Common parameters for nppiCompare functions include:

Parameters

pSrc1	Source-Image Pointer.
nSrc1Step	Source-Image Line Step.
pSrc2	Source-Image Pointer.
nSrc2Step	Source-Image Line Step.
pDst	Destination-Image Pointer.
nDstStep	Destination-Image Line Step.
oSizeROI	Region-of-Interest (ROI).
eComparisonOperation	Specifies the comparison operation to be used in the pixel comparison.

Returns

Image Data Related Error Codes, ROI Related Error Codes
