Abstract:

The work completed in the project dealt with the following areas of data compression and its applications the design and analysis of sophisticated methods for prediction based on data compression techniques, with applications to prefetching, caching, and locality management. Fast, practical, and code-efficient implementations of arithmetic coding and other coding methods, for use in text and image compression. New methods for choosing motion vectors yielding substantially better rate-distortion tradeoffs for video compression in video-conferencing applications. Duke University recently filed a patent application for the work on prediction.
