Opticflow shader
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 ). WebConstruction. opticFlow = opticalFlowLK returns an optical flow object used to estimate the direction and speed of an object's motion. opticalFlowLK uses the Lucas-Kanade algorithm and a difference filter, [-1 1], for temporal smoothing.. opticFlow = opticalFlowLK(Name,Value) includes additional options specified by one or more …

By definition, the optical flow is the vector field (u, v) verifying image1 (x+u, y+v) = image0 (x, y), where (image0, image1) is a couple of consecutive 2D frames from a sequence. This vector field can then be used for registration by image warping. To display registration results, an RGB ...
