Distortion-Optimal Transmission of Progressive Images over Channels with Random Bit Errors and Packet Erasures
We present a statistical optimization framework for solving the end-to-end problem of progressive transmission of images over noisy channels. We consider the impacts of transmissi...

Hybrid Fractal Video Coding with Neighbourhood Vector Quantisation
A hybrid video coding scheme which combines fractal coding with neighbourhood vector quantisation is reported. While fractal coding exploits the redundancy present in different sc...

Fast Near-Lossless or Lossless Compression of Large 3D Neuro-Anatomical Images
3D neuro-anatomical images and other volumetric data sets are important in many scientific and biomedical fields. Since such sets may be extremely large, a scalable compression me...

Multi-resolution Source Coding Using Entropy Constrained Dithered Scalar Quantization
In this paper, we build multi-resolution source codes using entropy constrained dithered scalar quantizers. We demonstrate that for n-dimensional random vectors, dithering followe...

On Optimal Multiresolution Source-Channel Coding across Degraded Broadcast Channels
Inspired by a converse result, the concept of "probabilistically matched" sources and channels is extended to sources subject to multiresolution coding and degraded broa...
