Cool! Rotoscoped animation doesn't have to be by hand anymore. So you guys think this is could be better then Rotoshop?
Looks like NPR/Painterly rendering is this API's killer ap.

EDIT:
According to the the vimeo page he will release it as open source. That was 4 months ago.
Maybe tritical can encourage him to release an AviSynth plugin as part of his research.

jep i especially like the NPR but also the Saliency Sharpening here http://www.gradientshop.com/demos/apps/ssharpen/image_results/www/pages/20060527-pic028-big.htm alone looks interesting and versatile usable, it seems to be a nice general Post Processing Deblurrer it looks absolutely non destructible to the edges or like a overdone sharpening (just a little to much black level enhancing) you just realize the blur has gone so the combination of the Deblocker and then the Saliency Sharpening must look Visually really amazing i guess :).

Deblocker looks very good IMO. Could be useful for reducing posterization as well.

very interesting work.especially sharpenning results. I am downloading the paper, and trying to write the code according it.

it seems to be very slow. the paper says "Our unoptimized C++ code currently spends a few seconds for one megapixel images and nearly one minute per video frame (at 800x600 resolution)", and suggests GPU solution.

Hi guys, I have contact the author. and he says that he will release the code soon - in a day or two.
so, any body add the algorithm to avisynth?
CruNcher, what do you think about it?

It makes very ugly haloing with some images :/

this has immense potential if we get someone like mugfunky/didee/tritical to implement the code in avisynth , gosh the pseudo relighting part was amazing , down with photoshop if this comes good for video's and images as well , yay ! , ctrl + v for me on this page , added in favourites , will keep on following it :)

one possible place to start looking for an emulation would be fft3dfilter's sharpen mode (which at negative values greater than -1 will give a good lowpass), and a lot of masktoolage.

just this line gives a "saliency-esque" look...

fft3dfilter(bw=128,bh=128,ow=64,oh=64,bt=1,sigma=0.,sharpen=1,smin=0,smax=100,scutoff=1/128.,wintype=0)

i'll have to play with masks and whatnot to get some of that NPR happening.
