warp #186

Is class Resample2d a warp operation class?

nikolausmayer commented 5 years ago

I am not sure what you mean by "warp operation". The Resample2d layer is a linear scaling operation, so I guess "yes", it is technically an edge case of image warping.

Thank you for your reply Warp operation,I think it is img1 to img2 by Optical flow diagram。 I don't find the code of warp operation, can you tell me.

Our warping layer implementation is in the flow_warp_layer files. Resample2d is not a warping implementation in our code. It serves an entirely different purpose: forcing input dimensions to multiples of 64 during the deeper layers.
