摘要: A very fast high-compression, high-fidelity, image coding technique termed visual pattern (VPIC) was recently introduced by the authors (1990). hierarchical version of VPIC (HVPIC) is developed here. In HVPIC, coded images improved fidelity relative to are generated, with increased compressions (routinely exceeding 20:1). Significantly, computational efficiency simple retained which utilizes at each resolution level. >
