  author={Andr{\'e}s Bruhn and Joachim Weickert and Timo Kohlberger and Christoph Schn{\"o}rr},
Variational methods are very popular for optic flow computation: They yield dense flow fields and perform well if they are adapted such that they respect discontinuities in the image sequence or the flow field. Unfortunately, this adaptation results in high computational complexity. In our paper we show that it is possible to achieve real-time performance for these methods if bidirectional multigrid strategies are used. To this end, we study two prototypes: i) For the anisotropic imagedriven… CONTINUE READING
