Question about large difference warping #123

chair2 chair5 flo2-5 warped Hello! I use the PWC-Net to calculate the optical from chair2 to chair5 and warped chair5 back to chair2 using the optical flow. However, the warped image is blurred. I want to know whether it is difficult to warp two images with large difference or it is my fault that my optical flow is wrong.

The first image is chair2 and second is chair5.
