FilterMinGetBufferSize

Computes the size of the working buffer for the minimum filter.

Syntax

IppStatus ippiFilterMinGetBufferSize_<mod>(int roiWidth, IppiSize maskSize, int* pBufferSize);

Supported values for mod:

8u_C1R	32f_C1R
8u_C3R	32f_C3R
8u_C4R	32f_C4R

Parameters

roiWidth	Image width (in pixels).
maskSize	Size of the mask in pixels.
pBufferSize	Pointer to the computed size of the buffer.

Description

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

This function computes the size of the working buffer required for theippiFilterMinBorderReplicate function. The buffer with the length pBufferSize[0] can be used to filter images with width equal to or less than roiWidth.

Return Values

ippStsNoErr	Indicates no error. Any other value indicates an error or a warning.
ippStsNullPtrErr	Indicates an error condition if the pointer pBufferSize is NULL.
ippStsSizeErr	Indicates an error condition if maskSize has a field with a zero or negative value, or if roiWidth is less than 1.
