METHOD OF DATA COMPRESSION INCLUDING COMPRESSION OF VIDEO DATA |
摘要 |
<p>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<SUB>i </SUB>(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.</p> |
