For improving accuracy of optical flow computation, we propose a new method to compute optical flow from both gray and color information. First, the Gauss filter is used to pre-filter the color image sequence. Then optical flow recovery is based on the method of neighborhood least squares using brightness information. And the weight coefficients of local neighborhood are determined by U and V channels...
It is a problem that the results are unstable when local method is used to estimate optical flow at smooth color points. A method was presented to estimate stability through the condition number of local coefficients matrix. And the color results of global smooth were used to replace the unstable results of local color method. The combined model was provided with the advantages of high precision of...
