中文摘要：

文章提出一种基于结构张量的变分光流计算方法。为了在光照突变下有良好的处理能力,设计的数据项由灰度守恒假设和二阶局部结构张量守恒假设组成,为了提高数据项的稳健性,引入非平方惩罚函数。为了使模型在图像边缘有不错的效果,设计的平滑项采用先各向同性平滑再各向异性平滑的策略,在低分辨率图像序列中采用各向同性平滑策略,在高分辨率图像序列中采用各向异性平滑策略。实验证明,本模型的光流计算结果比以往的变分方法有所改进。

英文摘要：

This paper proposes a variational calculation for optic flow based on structure tensor.To be effective in illumination changes,this paper uses gray and second-order local structure tensor constancy assumption as the data term;To improve the robust of the data term,this paper designs a non-squadratic penalizer.To be effective in the edge of moving objects,this paper uses both isotropic strategy and anisotropic strategy.The isotropic strategy is used in the low resolution and the anisotropic strategy is used in the high resolution.The experiment shows that the model proposed in this paper has improved compared to the previous variational model of optical flow calculation.
