More details about the algorithm can be found at . … Lucas-Kanade method computes optical flow for a sparse feature set (in our example, corners detected using Shi-Tomasi algorithm). OpenCV provides another algorithm to find the dense optical flow. It computes the optical flow for all the points in the frame. It is based on Gunnar Farneback's algorithm which is … Ver mais 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 … Ver mais 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 … Ver mais OpenCV provides all these in a single function, cv.calcOpticalFlowPyrLK(). Here, we create a simple application which tracks some points in a video. To decide the points, we use cv.goodFeaturesToTrack(). … Ver mais
Web26 de abr. de 2012 · Using OpenCV 2.4 beta, you have to look for the class BackgroundSubtractor and its subclasses in the video module documentation. Note also that optical flow can be realtime (or not very far) with good choices of parameters, and also with GPU implementation. On windows, you can use flowlib from TU Graz/Gpu4Vision group.
