WebIntroduction. This example streams images from an image acquisition device to detect motion in the live video. It uses the optical flow estimation technique to estimate the motion vectors in each frame of the live video sequence. Once the motion vectors are determined, we draw it over the moving objects in the video sequence. WebDescription. flow = estimateFlow (opticFlow,I) estimates the optical flow of the input image, I, with respect to the previous image. The function sets the previous image for the first run to a black image. After the first run, each new image, I, becomes the current image, and the image from the last run becomes the previous one. You can also ...
