【Abstract】 Discontinuities in optical flow field is one of the most important research contents in accurately estimation of optical flow field. The regularization for the optical flow field can be carried out by use of residual sum of squares in least-square or weighted-least-square algorithm, in this way the probability of the multi-mode motion containing in the calculation window can be reduced and the discontinuities of optical flow field can be solved, thus the algorithm has robustness. The calculation results show that the algorithm has the characteristics of simplicity, practice and fast operating speed.更多还原
