https://community.intel.com/t5/Intel-Integrated-Performance/Optical-Flow-with-16-bit/m-p/881339#M10232 The IppiPyramid contains pointers to 8 bit unsigned Images. But when i am using optical flow for 16 bit images how do i use the IppiPyramid. Do i need to use IppiConvert (does it result in loss in accuracy) or should i just cast the pointer as 8 bit images and still use 16 bit images.
