摘要: 基于光流计算的通用变分模型,建立小位移光流场计算的对偶方法。变分能量泛函中的数据项使用稳健估计的L1范数,规则项采用边缘保持的总变差项。采用对偶变量表示总变差项,克服基于传统总变差计算须引入小规则参数的问题,并得到较好的实验结果。该方法可应用到大位移光流计算和光流计算的高阶模型中。

Abstract: Dual method is presented for small optic flow computation based on variational models. Robust estimation form of L1 norm is used in data terms and the regularized terms use total variation of optic flows with edge preserving property. The dual variables for total variation terms avoid using small regularized parameters in classic total variation terms and get good results. This method can be extended to computation of large displacement optical flow and higher order models.

Key words: optic flow computation, dual method, variational method, total variation
