WebThis small motion in the image is called optical flow. Optical flow is usually considered in two ways, in the dense state, where the flow vector is calculated for each pixel, and in the feature-based state, which is calculated for the specific purposes for which it is intended. how many cups are in a liter of milkWebThe optical flow is estimated as the motion between two consecutive video frames. The video frame T at the given instant tcurrent is referred as current frame and the video frame T-1 is referred as previous frame. The initial value of the previous frame at time tcurrent = 0 is set as a uniform image of grayscale value 0.
