DATA COMPRESSION USING MATCHING PURSUITS

摘要

A method and apparatus for data compression comprising applying a de-correlating transform to multi-dimensional data to be compressed, then using a sequence of one or more one-dimensional matching pursuits algorithms to code the output of the transform. The invention finds particular application in video and still image coders, particularly real-time coders, those intended for use at very low bit rates, and those for which scalable bit rates are of importance.
