A Variational Calculation for Optical Flow Based on Structure Tensor

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.
