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 this problem, we allow the user to choose between mirrored texturing or label-driven texture synthesis – “texture-by-numbers” – on a part-by- part basis. ```

Oh great. Now we can make The Ring scene come alive. Merry Christmas.

No thanks. 1:46 was creepy enough!

This is a really cool technique that posing interesting questions about how 3D resources in the future will exist.

Will marketing companies release models and textures like we release different image formats now? Are there grest uses for quickly making video or 3D from a photo. IDK, really cool though.

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

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 noticeable.
