Given the first image and the forward flow, how can I perform forward warping to get im2?

I am afraid PWC-Net does backward warping, not forward warping:

pytorch-pwc/run.py

Line 149 in d8d55b2

tensorOutput = torch.nn.functional.grid_sample(input=tensorInput, grid=(self.tensorGrid + tensorFlow).permute(0, 2, 3, 1), mode='bilinear', padding_mode='zeros')

In your paper "Context-aware Synthesis for Video Frame Interpolation", you use forward warping, so will please release your code of this paper?
