Abstract

A new method is proposed when optical flow is estimated in a color image sequence. That is the indirect method exploiting Hue and Saturation as color invariance under motion, with differs from the straightforward method of using the color components as separate images ofthe same scene. Also the two color systems HSV and HLS are used for two reasons. Firstly, they have advantage over the traditional method in using the ratio of the color components as separate images of the same scene, so that they can avoid linearly dependent of color components. Secondly, they correspond to human vision since the two color systems have been developed for user and can represent the color characteristics. In order to prove the new method effective, computer simulation experiments were carried out while estimated the optical flow in color synthetic sequences and analysis their performance of two -frame color optical flow both qualitatively and quantitatively. The results showed that the new method yields accurate optical flow field estimation.
