RD-Optimization of Hierarchical Structured Adaptive Vector Quantization for Video Coding
This paper contains two contributions to very-low-bitrate video coding. First, we show that in contrast to common practice incremental techniques for rate-distortion optimization ...

A lagrangian optimized rate control algorithm for the H.264/AVC encoder
The H.264/AVC video coding standard has been recently proposed by the Joint Video Team of ITU-T and MPEG experts. The AVC encoder achieves video bitstreams at the same quality as ...

Matching pursuits based multiple description video coding for lossy environments
Multiple description coding (MDC) is an error resilient source coding scheme that creates multiple descriptions of the source with the aim of providing an acceptable reconstructio...

Highly scalable video compression with scalable motion coding
A scalable video coder cannot be equally efficient over a wide range of bit-rates unless both the video data and the motion information are scalable. We propose a wavelet-based, h...

Multiresolution 3D mesh compression
In this paper, we propose an efficient low complexity compression scheme for densely sampled irregular 3D meshes. This scheme is based on 3D multiresolution analysis (3D Discrete ...
