Computes the size of the working buffer for the maximum filter.
IppStatus ippiFilterMaxGetBufferSize_<mod>(int roiWidth, IppiSize maskSize, int* pBufferSize);
Supported values for mod:
8u_C1R | 32f_C1R |
8u_C3R | 32f_C3R |
8u_C4R | 32f_C4R |
roiWidth |
Image width (in pixels). |
maskSize |
Size of the mask in pixels. |
pBufferSize |
Pointer to the computed size of the buffer. |
The function ippiFilterMaxGetBufferSize 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 the ippiFilterMaxBorderReplicate function. The buffer with the length pBufferSize[0] can be used to filter images with width equal to or less than roiWidth.
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. |
