Optical flow for point cloud extraction

S-kewen opened this issue · comments

Thanks for your work, I found some point cloud interpolation works using PWC-Net to extract optical flow between point clouds, but none of them provided source code. I currently plan to reproduce these results, but I found that PWC-Net cannot be directly used to extract the optical flow of point clouds. I'm guessing someone is working on a problem related to mine, can you provide an idea? thanks.
