----------------------------------
Efficient processing of time-dependent shape information is important
for applications in computer animation, games, medical visualization,
and scientific computing. Temporal coherence of such shape data seems
to be the key element enabling all of our recent work in the
area. Temporally coherent animated meshes are the data
representations that we use in our recent work:
- we compress them to enable efficient storage and transmission,
- we extract them from temporally incoherent mesh sequences acquired
by others,
- we also aspire to acquire them directly from video sequences by
tracking surface templates in real-time.
In my talk, I will present all of these three recent projects with
examples and technical details.
