Parameters
pBGR
Pointer to the source image ROI.
bgrStep
Distance in bytes between starts of consecutive lines in the source image.
pYCC
Array of pointers to the destination image ROI in each plane.
yccStep
Distance in bytes between starts of consecutive lines in the destination image.
roiSize
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 the 24-bit
BGR
image
pBGR
to the
YCoCg
image
pYCC
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
.
