Parameters
- pSrc
- Pointer to the source image ROI.
- srcStep
- Distance in bytes between starts of consecutive lines in the source image.
- pDst
- Array of pointers to the destination image ROI in each plane.
- dstStep
- Distance in bytes between starts of consecutive lines in the destination image.
- roi
- Size of the source and destination ROI in pixels.
Description
This function operates with ROI (see Regions of Interest in Intel
IPP).
This function converts a
RGB
image pSrc
to the YCoCg
image
pDst
according to
the following formulas:Y = ((R + 2*G + B)+
2)/4
Co = ((R - B) +
1))/2
Cg = (( - R + 2*G - B) +
2)/4
Return Values
- ippStsNoErr
- Indicates no error. Any other value indicates an error.
- ippStsNullPtrErr
- Indicates an error condition if one of the specified pointers isNULL.
