FastMarchingGetBufferSize

Computes the size of the working buffer for the peak search.

Syntax

IppStatus ippiFastMarchingGetBufferSize_8u32f_C1R(IppiSize roiSize, int* pBufferSize);

Include Files

ippcv.h

Domain Dependencies

Headers: ippcore.h, ippvm.h, ipps.h, ippi.h

Libraries: ippcore.lib, ippvm.lib, ipps.lib, ippi.lib

Parameters

roiSize

Maximum image size (in pixels).

pBufferSize

Pointer to the computed size of the buffer.

Description

This function operates with ROI (see Regions of Interest in Intel IPP).

This function computes the size of the working buffer required for the ippiFastMarching function. The buffer with the length pBufferSize[0] can be used to filter images with width that is equal to or less than the parameter roiSize specified for the function ippiFastMarching.

Return Values

ippStsNoErr

Indicates no error. Any other value indicates an error or a warning.

ippStsNullPtrErr

Indicates an error condition if pBufferSize pointer is NULL.

ippStsSizeErr

Indicates an error condition if roiSize is lessthan 1.
