The kernel of improvement is that fractal predictive encoding is imported into mzte , and wavelet coefficient is encoded in zte mode or in fractal mode according to in which mode the encoding error is minimum 這種改進的核心思想是通過引入分形預測編碼方法,根據具體情況,綜合使用零樹熵編碼和分形預測編碼方法對圖像小波分解系數進行編碼。
This paper propose a improvement method of mzte , adopted in mpeg - 4 for encoding stilltexture . firstly , the basic conception of image / video compression is provi - ded , and then the conception of wavelet decomposing and fractal predictive encoding , lastly , mzte and it ' s improvement is illuminated detailedly 首先分析了圖像及視頻壓縮的技術現狀,論述了小波分解及在圖像壓縮中的應用、分形預測編碼的理論和方法,然后重點對mzte進行了深入的論述分析,最后對mzte的改進作了詳細說明。
