Abstract: Object tracking by using single object feature often results in a poor performance in robustness.In this paper，an object tracking method based on multi-features fusion is proposed，it utilizes both color and motion edge feature，and performs a probability fusion in particle filter framework.Experiment results show that by using the proposed method，when one of the features loses discrimination ability for tracking，other features are still able to track the object stably.Moreover，it is simple and very suitable to be applied to deal with tracking problems in complex scene.
