Can you explain a little bit more about the matting loss?

[yuhaoliu7456]

In "Matting Laplacian [22] may result in blurry images when it is used with another network like one with an encoder-decoder architecture. But it does not have this issue in CAP-VSTNet, since the bijective transformation of reversible network theoretically requires all information to be preserved."

I'm curious about the relationship between the bijective transformation of a reversible network that theoretically needs to preserve all information and the image blur caused by Laplacian matting? Even after reading this paragraph several times, I still cannot fully understand your point here.

So can you please kindly help me figure this out?

Thanks.
