It's certainly interesting. Thanks! Just now that I had lost interest :)

You're right it's not usable for realtime processing. It needs thousands of 
itterations. I have the parrot example running for minutes now and the 
fence is still mostly vissible. Parts are gone though and it looks good. 
So, for image reconstruction, it's useless, unless you can bear 1 frame per 
hour or something. Even if you limit the region you reconstruct, it will 
still take thousands of itterations and maybe five to ten minutes to 
reconstruct only one frame.

But, I have also run the denoising examples, and that could be interesting 
as a high quality denoiser. After 40-60 itterations, all the noise is gone 
and the result looks very good. It will still be slow as hell (maybe one 
frame per ten seconds), but for encoding small video clips, it might just 
be feasible.

PS Don't top post and don't quote more than is needed.
