【Abstract】 The fast algorithm for moving objects detection and tracking in sequential images is studied in this paper.The fading memory recursive least-square based on Kalman filter is discussed,and it is applied to rebuild image background.Then the moving object is extracted hy the method of images difference.A simplified equivalent gray value projection algorithm is proposed for object centroid calculation.The memory extrapolation is used to achieve target tracking.The algorithm is simulated.The re- sults show that the algorithm proposed in this paper is simple,effective,high speed,and strong adaptability,So this algorithm can be used for moving object detection and tracking in sequences of monocular images.更多还原
