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 … See more 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 … See more 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 … See more 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(). … See more WebMar 17, 2013 · 当人的眼睛观察运动物体时,物体的景象在人眼的视网膜上形成一系列连续变化的图像,这一系列连续变化的信息不断“流过”视网膜(即图像平面),好像一种光的“流”,故称之为光流(optical flow)。. 光流表达了图像的变化,由于它包含了目标运动的信息 ...
