Hello, In the article, you did explain the refinement of flow in the Appearance flow estimation network. There are two places, which I did not understand when you said that you added residual flows but in code, as I actually see, that you did grid sample on flows. Could you please explain why did you do such an operation not only on the clothes to warp it but on the flows themselves?

Hi, as the function apply_offset() turns flow into grids for sample, we actually did grid sample on grids.
