英文摘要：

This paper uses the analytic wavelet and M-estimator to solve the optical flow restriction equation, and gets a high precision and robust algorithm for optical flow computation. After introducing the extended accumulative optical flow, the paper puts forward the computational strategies for it, and obtains a robust moving object detection algorithm. The experimental results show that the algorithm can detect moving objects precisely, including slow or little objects, and also solve the occlusions preferably.
