Word-Based Statistical Compressors as Natural Language Compression Boosters
Semistatic word-based byte-oriented compression codes are known to be attractive alternatives to compress natural language texts. With compression ratios around 30%, they allow di...

Quantization of Overcomplete Expansions
The use of overcomplete sets of vectors (redundant bases or frames) together with quantization is explored as an alternative to transform coding for signal compression. The goal i...

Binary compression rates for ASCII formats
Geometry compression for VRML has been an important item on the wish-list of the Web3D Consortium since 1996. It was widely understood that a binary format would be required to al...
