will speak on
Environment and Alpha Matting from Image Sequences
Alpha matting is a technique for combining two layers of video, one on top of the other, by associating an opacity with each foreground pixel. When the layers contain optically active components (e.g. a lens) the background can no longer be composited plainly and a more complex phenomenon needs to be modeled. Environment matting is a technique for modelling the complex light-transport properties of real-world optically active elements:
transparent, refractive and reflective objects.
In this talk I will show how both these methods can be automated to
produce high quality compositing. We compute both alpha and environment
maps from multiple images and use them to create new composited images
with high quality.
The lecture will take place in the
