Rate distortion analysis of leaky prediction layered video coding using quantization noise modeling
Unlike conventional layered scalable video coding, leaky prediction layered video coding (LPLC) introduces a leaky factor , which takes on values in the range between 0 and 1, to ...

Video coding using a deformation compensation algorithm based on adaptive matching pursuit image decompositions
Today's video codecs employ motion compensated prediction in combination with block matching techniques. These techniques, although achieving some level of adaptivity in thei...

Navigating in Manhattan: 3D orientation from video without correspondences
The problem of inferring 3D orientation of a camera from video sequences has been mostly addressed by first computing correspondences of image features. This intermediate step is ...

Text to visual synthesis with appearance models
This paper presents a new method named text to visual synthesis with appearance models (TEVISAM) for generating videorealistic talking heads. In a first step, the system learns a ...
