It seems like this could /also/ be used for video by using this technique along with residual coding.
- nullc 6y ago> It seems like this could /also/ be used for video by using this technique along with residual coding. Not trivially-- in the pixel or DCT domain the residual would almost certainly be extremely non-sparse, and would take a lot of bits-- potentially similar to just sending an image (for a given target MSE level). Consider, edges (other than the keypoint controlled ones) aren't even in exactly the same place-- so the residual doesn't just need to code the edge, it needs to code it twice. This has been one of the big impediments in using 'synthesis' techniques in video coding generally. It might be possible to code a residual in some latent NN space and get more useful results, however.
