https://community.intel.com/t5/Intel-Integrated-Performance/Extract-image-coordinates-from-masked-images-no-pack-extraction/m-p/905704#M13417 Hi,<BR /><BR />I have the following problem. I want to extract some images coordinates from a Ipp8u masked image, e.g. corner points. Instead of using a n^2 for loop checking with pixel is set, I want to create a coordinate image, encoding the x-y coordinates in some way, let's say in a Ipp32u image. Now I want to use something like ippiCopy on masked pixels, but I want to have the resulting data packed as a continous stream. There is a method in the MKL called vsPackM, but it expects the mask to be Ipp32u and I want to avoid converting the mask. I have searched the whole documentation but I couldn't find anything, perhaps I missed a function ...<BR />Does anybody has a suggestion ?<BR /><BR />Thanks and best regards,<BR /><BR />Matthias Grundmann<BR /> Sat, 14 Oct 2006 03:07:40 GMT grundman 2006-10-14T03:07:40Z https://community.intel.com/t5/Intel-Integrated-Performance/Extract-image-coordinates-from-masked-images-no-pack-extraction/m-p/905704#M13417 Hi,<BR /><BR />I have the following problem.
