https://community.intel.com/t5/Intel-Integrated-Performance/Problems-with-ippiOpticalFlowPyrLK/m-p/886930#M10941 I'm trying to use the ippiOpticalFlowPyrLK function. Somehow it isn't working and the status array is full of 10s. That warning is ippStsJPEGMarker: JPEG marker was met in the bitstream, which seems pretty odd to me. I am using the example copied straight out of the volume 2 of the IPP documentation (example 14-5: Pyramid Building and Optical Flow Calculation).<BR /><BR />None of the functions return an error, but the status parameter in the call to ippiOpticalFlowPyrLK indicates that something's going wrong. <BR /><BR />Does anybody have experience with this function? By the way, I am still using version 6.0 of IPP.<BR /> Tue, 25 Aug 2009 23:59:39 GMT chris_t 2009-08-25T23:59:39Z https://community.intel.com/t5/Intel-Integrated-Performance/Problems-with-ippiOpticalFlowPyrLK/m-p/886930#M10941 I'm trying to use the ippiOpticalFlowPyrLK function.
