| Abstract | ||
| An approach is developed for computing optical flow in the differential framework for global models. This is achieved using schemes for the computation of the derivative using 4-point central differences filter. The proposed algorithm is compared with the most recent algorithm that is based on multiwavelet and it is found that the proposed algorithm is better than that based on multiwavelet in terms of results and required execution time. The algorithm developed in this paper is performed using MATLAB version 7 and implemented on Pentium 4, 1.7 GHz, 256 Mbyte RAM computer. | ||
