Optical flow in video processing
WebNov 29, 2024 · Determining the optical flow of a video is a compute-intensive task essential for computer vision. For achieving this processing in real time, the whole algorithm deployment chain must be thought of for efficiency first. The development is usually divided into two parts: first, designing an algorithm that meets precision constraints, then, … 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 ...

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.
