METHOD OF DATA COMPRESSION INCLUDING COMPRESSION OF VIDEO DATA

摘要

A data processing system includes a subband decomposition of a source signal by encoding of the significant pyramid-type subband representation. During the encoding process, M-array is used for initialization of set of arrays S_i (arrays of solution bits), which define the order of creating output data streams. Output data streams contain an encoded significance map and values of (significant) non-zero subband decomposition coefficients adapted for successive quantization and entropy encoding.
