WebMany video enhancement algorithms rely on optical flow to register frames in a video sequence. Precise flow estimation is however intractable; and optical flow itself is often a sub-optimal representation for particular video processing tasks. In this paper, we propose task-oriented flow (TOFlow), a motion representation learned in a self ... 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 ). …
WebAug 1, 2009 · The motion features captured by optical flow provide dynamic information, and so optical flow is widely used in various video processing tasks such as motion … WebOpenCV is a universal image processing framework. It takes in frames, not compressed video, for its algorithms. You can certainly write a video decoder that also hands out info about displacement from the codec to openCV – but that will be very codec-specific and thus isn't in scope of openCV itself.
