Very impressive. Not to be a cynic, but how long before someone starts turning people inappropriately into frog marching saluting Nazis?! Or giving them an unfortunate Fortnite "bounce". I haven't read the paper, but am curious how they get the face profile right (given the information is absent in the 2D source). Perhaps they set that manually or some kind of average face, but if it's off it would be quite noticeabl…

How long? 17 seconds.

That's probably meant to be cute or optimistic, I know they're not making fun of anything, but I still find it very tasteless.

Why not just use your own drawings and photos? I generally don't like how art is often used for these kind of things.

That artwork is basically saying kids should be flying kites, rather than being bombed by drones while they cry in terror.

I find playing around with that tasteless, to put it mildly and charitably, and I said nothing about it, after seeing it and puking into my mouth a little -- if walking on egg shells, and calling it tasteless to be generous, is punished anway, I may as well be honest, and I'm still biting my tongue on just how tacky CS meeting art is 99% of the time, that's tasteless too but in the actual meaning of the word, just unskilled, garish, time and time again demonstrating that developed art comes from developed persons, not from developed tools -- right after the story was posted and there were no comments. I just shook my head basically, kept it to myself. But when I later saw the question of how long it'll take before someone does something inappropriate with it, I just had to point it out.

What guideline was I violating? How was my comment not a contribution? If you disagree with it being tasteless, if I overlooked or misrepresented something, where are the words?

At first I thought it was something that could be done in real time. Like, you walk up to any painting with the AR glasses on, do the gesture and it would extract a figure and animate it. On closer inspection, the artworks are also virtual in their example videos. I was hoping they would be real, it feel less impressive when none of it is really present.

I'm wondering how they texture the backside of animated characters?

Check out supplementary material [1]. The supplement mentions this about backside texturing: ``` Texturing the back of the body is more difficult, as we have no direct observation of it. One approach is to sim- ply mirror the front texture onto the back. This mirrored- texturing produces reasonable results in some cases (e.g., arms), but undesirable results in others (face appears on the back of the head). To address…

You can see this in effect in the Picasso AR demo at around 0:45 and 4:50

Looks super cool. I wonder if multiple subjects in the same photo could be animated. I sorta expected that from the picture with the Beatles ( assuming that gang of 4 Brittish looking guys was them )

The sequence beginning at 1:58 is (I think) a still from the Hard Day's Night movie. The sequence beginning at 4:29 uses the Help! album cover

Yes it is.
