Use Lucas-Kanade optical flow algorithm to compute optical flow between picture8.jpg and picture11. Display optical flow vectors on picture .Use optical flow vectors computed in previous part o perform moving object segmentation.First, compute optical flow magnitude for each pixel, and then apply a proper threshold to optical flow magnitude image for moving object segmentation. Display the optical flow magnitude image, and binary segmented image. I need code for this question (OpenCV-Python). Please add commends so that I can understand.
