i run nvmedia sample app flowsense – The test application demonstrates the optical flow pipeline.
when input 19201080 image and calculate 1x1 grid optical flow, the cost time is about 10 second/frame
when input 19201080 image and calculate 2x2 grid optical flow, the cost time is about 23 millsecond/frame.
Is OFA not support 1x1 grid optical flow for 1920*1080 input image?
