This is the single most impressive example of image processing I've seen to date.

I think they patchmatch algorithm they use to fill the background is cooler, to be honest. Check out their video: https://vimeo.com/5024379#at=0

nothing new though, photoshop has had content aware fill for a while

most impressive thing for me about this demo is how good the shape detection is (seems way better than magnetic lasso in Photoshop), and how they brought different pieces of separate technologies together to such a fluid experience. And how the presenter sounds about 12.

These guys/girls know what they're doing.

Is there a reason many of these crazy image processing technologies never seem to have actual demos or releases? The only exception I can think of it the "smart erase" idea, which has been implemented in Photoshop as well as Gimp.

What other image manipulation software do you follow closely?

If you marked shadows and associated them with their source, could you then recover the light source(s) and be able to remove the baked shadows and recast them in real time? Also, with the shiny objects, could you specify the material properties and have it "back out" the reflection such that the reflection was recomputed as you moved the shape around?

Yes, there are other projects that do things like insert a synthetic object into a scene, with natural in-context lighting that is inferred from the light gradients on other objects in scene.

Yes, here's a cool demo video from 2011 SIGGRAPH Asia...can't even imagine how much more things have progressed since then:

This is an academic project - the main goal is typically to publish a paper, not to release a demo or product.
