| Abstract: | In this paper,optical flow estimation for color image sequence based on gradient field is proposed,in which the optical equation is established at gradient field of color images to weaken optical estimation errors caused by illumination variations combining with the color information.Three groups of experiments show that the proposed method is more accurate and robust. |
| Keywords: | optical flow gradient field color images generalized dynamic image model |
