MinEigenValGetBufferSize

Calculates size of temporary buffer for the function ippiMinEigenVal.

Syntax

IppStatus ippiMinEigenValGetBufferSize_32f_C1R(IppiSize roiSize, int apertureSize, int avgWindow, int* pBufferSize);

roiSize: Size of the source image ROI in pixels.
apertureSize: Size (in pixels) of the derivative operator used by the function, possible values are 3 or 5.
avgWindow: Size of the blurring window in pixels, possible values are 3 or 5.
pBufferSize: Pointer to the variable that returns the size of the temporary buffer.

This function operates with ROI (see Regions of Interest in Intel IPP). This function calculates the size of a temporary buffer to be used by the function ippiMinEigenVal.

The parameters apertureSize and avgWindow must be the same for both functions ippiMinEigenValGetBufferSize and ippiMinEigenVal.

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 roiWidth has a zero or negative value, or if apertureSize or avgWindow has an illegal value.
