OpenCV中稠密光流算法总结

WebOPTFLOW_FARNEBACK_GAUSSIAN Use the Gaussian filter instead of a box filter of the same size for optical flow estimation. Usually, this option gives z more accurate flow than with a box filter, at the cost of lower speed. Normally, winsize for a Gaussian window should be set to a larger value to achieve the same level of robustness.
