Interesting use of the tech, there. I'd be interested in investigating the cases where it breaks, and how robust it is though. I've seen (and made) enough tech demo videos to know that you can hide a lot by controlling the conditions when recording.
*nod* Depends a lot on the scene model, and how long your hand is occluding the space. Background subtraction that elegantly handles occlusion is a mite tricksy, especially in realtime.

No indication of the hardware required to do this, or whether it works on anything other than a pretty smooth and uniform background, which is what they chose (and even then it occasionally had glitches).
Yeah - I've seen the Photoshop filter that this is remarkably similar to (and the original siggraph video that first brought the technique to light) and there are definitely situations where it breaks down.
Very cool when you've got something on a reasonably uniform background though.
and when they moved the tablet too quickly, artifacts increased - to the point where the dark junk (including a phone) on the desk actually broke back into the frame for a moment.
proof-of-concept is interesting. but the artefacts make it quite noticeable - especially when the viewpoint shifts around the 'erased' object (or more accurately, the smudged out region of view.
