Design and Analysis of Lossless and Lossy Data Compression Methods and

摘要

The work completed in the project dealt with the following areas of datacompression 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.
