Three-dimensional shape-adaptive discrete wavelet transforms for efficient object-based video coding
In this paper, we present an object-based coding scheme using three-dimensional shape-adaptive discrete wavelet transforms (SA-DWT). Rather than straightforward extension of 2D SA...

Joint algorithm-architecture optimization of CABAC to increase speed and reduce area cost
To address the increasing demand for higher resolution and frame rates, processing speed (i.e. performance) and area cost need to be considered in the development of next generati...

A Stochastic Model for Video and its Information Rates
We propose a stochastic model for video and compute its information rates. The model has two sources of information representing ensembles of camera motion and visual scene data (...

Efficiency Improvements For A Geometric-partition-based Video Coder
H.264/AVC has brought an important increase in coding efficiency in comparison to previous video coding standards. One of its features is the use of macroblock partitioning in a t...
