Border artifacts about patch-dm

[zh-ding]

Hi, thanks for the questions.

1. Yes, that's correct. During the training the border artifacts will gradually decrease.
2. Sorry I may not fully understand your question. Is the image collage output (output nonshift) you mean here the output that does not use the feature collage mechanism?

Thanks for your reply XD
So return contains two outputs, pred1 is the output with feature collage, and pred2 is the direct output without feature collage (from my understand) so ideally shoud the pred2 stitch in imagespace (and take the center 64 * 64) be similar to the pred 1 output ideally?

Thanks for the clarification. Yes we don't have specific constraints on these two but as they're both used to calculate the loss with the groundtruth so there are indirect constraints applied on them. The main point here is to let the decoder fuse the collaged features from the encoder to alleviate the border artifacts.
