MaxEvery

Computes maximum value for each pair of pixels of two images.

Syntax

IppStatus ippiMaxEvery_<mod>(const Ipp<datatype>* pSrc, int srcStep, Ipp<datatype>* pSrcDst, int srcDstStep, IppiSize roiSize);

Supported values for mod:

8u_C1IR	16u_C1IR	16s_C1IR	32f_C1IR
8u_C3IR	16u_C3IR	16s_C3IR	32f_C3IR
8u_C4IR	16u_C4IR	16s_C4IR	32f_C4IR
8u_AC4IR	16u_AC4IR	16s_AC4IR	32f_AC4IR

Parameters

pSrc	Pointer to the first source image ROI.
srcStep	Distance in bytes between starts of consecutive lines in the first source image.
pSrcDst	Pointer to the second source and destination image ROI.
srcDstStep	Distance in bytes between starts of consecutive lines in the second source and destination image.
roiSize	Size of the image ROI in pixels.

Description

The function ippiMaxEvery is declared in the ippi.h file. It operates with ROI (see Regions of Interest in Intel IPP).

This function computes the maximum value for each pair of the corresponding pixels of two source images pSrc and pSrcDst, and stores the result in the pSrcDst:

pSrcDst(i, j) = max(pSrc( i,j), pSrcDst(i, j)).

Return Values

ippStsNoErr	Indicates no error. Any other value indicates an error or a warning.
ippStsNullPtrErr	Indicates an error condition if one of the specified pointers is `NULL`.
ippStsSizeErr	Indicates an error condition if roiSize has a field with zero or negative value.
ippStsStepErr	Indicates an error condition if srcStep or srcDstStep is less than roiSize.width*<pixelSize>.
ippStsNotEvenStepErr	Indicates an error condition if one of step values for floating-point images are not divisible by 4.
