发帖数: 166 | 1 my classmate is doing his thesis, his 'idea' is that given a sequence of
vedio(live action, handdrawing animation, or CG animation), then he will try
to extract some information(like the contour or position, or any porperties,)
from the sequence, then he will use NURBS to construt a 3d model based on
the information, then he will manipulate the shape of the model
abitrorily
, the vedio sequence will change accordingly. basically it's pretty much like

a vitual avatar on a video. Then you can some way manitipulate the virtual
avatar. Segmentation technique so far is still not that good to cut the video
object and control it arbitaryly. Especially when you want to have a 3-D
avatar.
Some research use the information get from video and generate a kind of "skin"
and paste it on an avatar, so it looks like a real video object. There are
