METHOD FOR ENCODING, COMPRESSED IMAGES IN PARTICULAR, IN PARTICULAR BY RANGE CODER OR ARITHMETIC COMPRESSION

摘要

Method for encoding a string of symbols using several models of the arithmetic or range coder type and comprising steps where: - each model is associated with a belonging criterion symbol, - the string is traversed so as to determine, for each symbol, the encoding model to which it belongs as a function of the criteria; then, - a probability of occurrence of each symbol in the corresponding model is determined; then, - the string is traversed while encoding each symbol successively; and, - a file is constructed on the basis of the code thus obtained.
