Because I don't have any luck in using the ippiMinEigenVal_8u32f_C1R function, I need to ask you a question:
The problem is, that I always get a ippStsSizeErr as return value. Citing the manual, this is the case if the roiSize is zero or negativ or apertureSize or averageWindow is 3 or smaller. But I can for sure deny that. So what can be a problem then?
