RGBToYCoCg

Converts a RGB image to the YCoCg color model.

Syntax

IppStatus ippiRGBToYCoCg_8u_C3P3R(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst[3], int dstStep, IppiSize roiSize);

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.
roiSize	Size of the source and destination ROI in pixels.

The function ippiRGBToYCoCg is declared in the ippcc.h file. It 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

ippStsNoErr	Indicates no error. Any other value indicates an error.
ippStsNullPtrErr	Indicates an error condition if one of the specified pointers is NULL.
