Introduction to Motion Estimation with Optical Flow

WebJan 8, 2013 · Optical flow is the pattern of apparent motion of image objects between two consecutive frames caused by the movement of object or camera. It is 2D vector field where each vector is a displacement vector showing the movement of points from first frame to second. Consider the image below (Image Courtesy: Wikipedia article on Optical Flow ). WebDec 5, 2024 · Optical flow is calculated on a dedicated hardware unit in the GPU silicon which leaves the streaming multiprocessors (typically used by CUDA programs) free to perform other tasks. The optical flow hardware returns fine grained flow vectors with quarter-pixel accuracy.
