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.
