Under complex environment, it is difficult to track target successfully by single feature. To solve this problem, the paper propose a novel object tracking approach which fuses color and SURF(Speeded Up Robust Features) in the frame of particle filter. SURF remain invariant for illumination, scale and affine. Add color to make up for the shortcoming(SURF is based on image gray scale information.). It not only maintains the characteristics of SURF, but also makes use of the image color information. The experimental results prove that the proposed method is real-time and robust in different scenes.
