A Moving Objects Detection Algorithm Based on Three Frame Difference and Sparse

Moving Objects detection is an important research of computer vision. Optical flow method is a main way, but it is limited to use because of its complexity. A moving objects detection algorithm based on three-fram difference an optical flow is proposed. the calculation of optical flow is simplified. Harris corners are detected and then only the corners are selected to compute the optical flow information, which reduce the algorithm's complextiy. Because the detected moving target area is not cmp
