  • Method for lossless data compression using greedy sequential context-dependent grammar transform
    Patent number: 6801141
    Abstract: A method of lossless data compression is provided which uses a grammar transform to sequentially construct a sequence of greedy context-dependent grammars from which an original data sequence can be recovered incrementally. The data sequence is encoded using any one of a sequential context-dependent method, an improved sequential context-dependent method, and a hierarchical context-dependent method.
