How to save flow map #3

How to save your gaussian flow map in png.

Zerg-Overmind commented 7 months ago

Since the size of Gaussianflow is H×W×2, which is the same as optical flow, you can visualize flow map the same as optical flow. You may need the function in this file for visualization.

Is the pre-computed optical flow in your code using forward flow or backward flow? Does it utilize an occlusion mask? Thanks

Hi, please refer to our paper for the details. It should be forward flow: t_1 -> t_2 where t_2 = t_1 + 1
