WebI've noticed this problem too. Under cv::calcOpticalFlowPyrLK most of the features are well tracked, but some aren't. This failed output points are many times too distant from the input points and don't follow the same flow of their neighbours.

In this chapter, 1. We will understand the concepts of optical flow and its estimation using Lucas-Kanade method. 2. We will use functions like cv.calcOpticalFlowPyrLK()to track feature points in a video. 3. We will create a dense optical flow field using the cv.calcOpticalFlowFarneback()method. See more Optical flow is the pattern of apparent motion of image objects between two consecutive frames caused by the movement of object … See more OpenCV provides all these in a single function, cv.calcOpticalFlowPyrLK().
