Foil 47 T2: Compression - Motivation

From Master Foilset for Collaborative and Interactive Visualization Project First Review Review Meeting at Rome Laboratory -- 31 January 1996. by Geoffrey C. Fox * See also color IMAGE
Compression technology decreases (by factor 20-200) the time and cost of transmission and storage requirements eliminating spacial, spectral and temporal redundancy
Evaluation of several image compression (JPEG, JBIG, Fractal, Wavelets) and video compression (MPEG, motion JPEG, H.261/263, MVC1, etc) technologies show great potential of wavelet-based methods
Wavelets : comprehensive, modern approach to advanced signal analysis and processing
Public domain software (EPIC, H-compress, Khoros Toolkit) - poor quality
Commercial products of high quality (AccuPress) available but without source and API and so cannot be integrated into other components such as VRML texture maps, digital video etc.
To proceed with the project we need full access to the wavelet based engine for compression/decompression of images and movies
