https://community.intel.com/t5/Intel-Integrated-Performance/ippiMinEigenVal/m-p/956823#M19155 Hallo<BR /><BR />Because I don't have any luck in using the ippiMinEigenVal_8u32f_C1R function, I need to ask you a question:<BR /><BR />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?<BR /><BR />Greetings<BR />Gerd Tue, 25 May 2004 00:25:22 GMT gmayer 2004-05-25T00:25:22Z https://community.intel.com/t5/Intel-Integrated-Performance/ippiMinEigenVal/m-p/956823#M19155 Hallo<BR /><BR />Because I don't have any luck in using the ippiMinEigenVal_8u32f_C1R function, I need to ask you a question:<BR /><BR />The problem is, that I always get a ippStsSizeErr as return value.

Actually, bad argument conditions are:<BR />One of pointer arguments is 0<BR />roiSize has non positive field<BR />Step is less than roiSize.width*<PIXELSIZE><BR />Step is not multiple of *<PIXELSIZE><BR />apertureSize or averageWindow is not 3, 5 or 7 (Sobel and Blur kernel sizes, supported in ippCV)</PIXELSIZE></PIXELSIZE></P> <DIV>Regards,<BR /> Vladimir</DIV> Tue, 25 May 2004 16:57:53 GMT https://community.intel.com/t5/Intel-Integrated-Performance/ippiMinEigenVal/m-p/956824#M19156 Intel_C_Intel 2004-05-25T16:57:53Z
