Parameters
- 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.
Description
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
.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 isNULL.
- ippStsSizeErr
- Indicates an error condition ifroiWidthhas a zero or negative value, or ifapertureSizeoravgWindowhas an illegal value.
