Motoin Capture Cartoon paper : While the idea of "capturing" the animation off an existing 2D animation sequence sounds great, the way the paper presents it, there seems to be a lot of user input and prior assumptions necessary to make it work (contours need to be provided, or assumptions about region colour is made). Also, extending the motion to 3D sounds costly and inaccurate. Overall, it's great to be able to reuse animations and apply them to create new ones, but it seems like there is almost as much work involved as doing it yourself to begin with. -- Roey Flor

(Motion signal processing) I usually find it quite interesting to see techniques discovered and developed in one field applied in another, but in this case, I found the results less than satisfying. Watching these animations in action may have been more convincing, but the descriptions and figures did not seem like very impressive results, and on top of this, their methods introduce constraint violations which almost seem to outweigh the benefits. What they believe "to be the most useful" of their techniques, motion displacement mapping, looks like an awkward and unintuitive method way of modifying a motion. I would think that directly modifying a pose of the character, and seeing where that new pose lies on several motion signals may make this method more approachable. -- H. David Young

(Turning to the masters: motion capturing cartoons) So much of the technique shown in this paper requires a lot of human involvement that I am curious as to when the motion should be recovered and when it would be more efficient to recreate it. I also found it kind of funny that they mention having data from a cartoon made with a computer tool; if such data was available from the original tool, I would think there would be much more affective ways to re-target the motion. -- H.
