Still pix only, it would appear, but there may be hope for all those nice-but-censored videos

(includes link to developers page with source code)

addition: didn't seem to do anything to the censorship blurring on some caps from the Zenra Swan Lake, so maybe we'll have wait longer :(

I am not very geeky, in fact I tend to panic under the technological avalanche. What I am interested in learning about this "de-blurring" technology, however, is whether it would be able to improve the quality of videos such as the Behrens Salome (Madrid 1986) or the Farley Salome (Caracas 1980). I suspect that the answer to my question is "No," for the same reason that it is impossible to obtain an in-focus print from an out-of-focus negative in film photography.

I don't see how this could work when the blur actually is in the original print. All this software probably does is replace the blurred sequences by unblurred pixels in the vicinity. It probably can't add detail to something that's masked.

I haven't managed to get it to do anything useful with stills, so you guys are probably right, but the original version was supposed to undo certain kinds of software blurring (would depend on the exact algorithm used). :(

I may be wrong, but going by the usual standards, you can only work with what's in the original print. So if the print is blurred and lacks the necessary pixels in certain regions, the software usually can't do anything about it, since the blur doesn't give up the underlying pixel informations.

And another little step:

Getting sharpness out of video tapes from the nineties and blur-censored Japanese porn videos will probably require a lot of AI, beyond the current state of the art, and raising questions of 'authenticity': is it really NoS if the performer was actually naked but the image you're staring it is heavily enhanced by general information about what the obscured parts look like?

No i don`t think it is. More like total overkill :D

More progress perhaps? Quite possibly not really, of course

But from my (very) slim and dim knowledge of such things, the kind of method employed well be able to sharpen up blurry VHS performances of classic performances.
