Three commixed still image coding algorithms are proposed based on them and such ideas as : zerotree coding , wmse ( which is based on mankind visual characteristics ) , classified vector quantization with different vector structures and classification methods . the chapter gives the principium analysis , realization schemes and simulation results of the proposed algorithms 在此基礎(chǔ)上,結(jié)合零樹編碼思想,以及基于人眼視覺特性和分類矢量量化的思想,根據(jù)不同的矢量構(gòu)成和分類方法提出了三種混合型靜止圖像編碼方法,給出了算法原理的分析、實現(xiàn)方案和仿真結(jié)果,最后對本章方法作出分析總結(jié)。
