Previously the pyramid was done with a rescaling factor of 2 (implied by the use of pyrDown). This often leads to inferior results compared to a scale step of e.g. 0.8 (a factor of 2 is obviously faster). This commit makes the scale step configurable and uses a resonable default value. The other change in this commit is that median filtering is added. This is not described in this paper but it is done in the author's implementation. (See e.g. "Secrets of optical flow estimation and their principles", Sun et al., CVPR 2010) This serves as periodic outlier removal during optimization, leading to smoother flow fields while preserving motion edges. This includes splitting the optimization loop into two loops. |
