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 roi);

Domain Dependencies
Headers: ippcore.h, ippvm.h, ipps.h, ippi.h
Libraries: ippcore.lib, ippvm.lib, ipps.lib, ippi.lib
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 is NULL. |
