Parameters
pSrc1, pSrc2 |
Pointers to the source image ROIs. |
src1Step, src2Step |
Distances in bytes between starts of consecutive lines in the source images. |
pDst |
Pointer to the destination image ROI. |
dstStep |
Distance in bytes between starts of consecutive lines in the destination image. |
roiSize |
Size of the source and destination ROI in pixels. |
ippCmpOp |
Compare operation to be used for comparing the pixel values. |
Description
This function operates with ROI (see Regions of Interest in Intel IPP).
This function compares the corresponding pixels of ROI in two source images pSrc1, pSrc2 using the ippCmpOp compare operation, and writes the results to a one-channel Ipp8u image pDst. If the result of the compare is true, the corresponding output pixel is set to an IPP_MAX_8U value; otherwise, it is set to 0.
Return Values
ippStsNoErr |
Indicates no error. Any other value indicates an error or a warning. |
ippStsNullPtrErr |
Indicates an error condition if one of the specified pointer is NULL. |
ippStsSizeErr |
Indicates an error condition if roiSize has a field with zero or negative value. |
ippStsStepErr |
Indicates an error condition if src1Step, src2Step, or dstStep has a zero or negative value. |
