解釋
埃斯科特-
Experimental results show that the model can achieve higher psnr than 3d - escot. while at the same time keeping all the advantages of 3d - escot
實驗結果表明：利用這種模型獲得的psnr高於3d - escot模型。同時也具有3d - escot模型的優良性質。 -
Experimental results also show that for every quantization width, every scale in time and every scale in space, 3d - pcw not only achieves higher compression rate but also costs less time than 3d - escot
實驗數據也表明，對于每個量化幅度和每個空間及時間解析度， 3d - pcw不僅獲得了比3d - escot更高的壓縮比，而且演算法執行所需要的時間也更少。 -
Inspired by typical coding schemes such as ezw, spiht, ebcot, 3d - iezw, 3d - spiht and 3d - escot, a new context model of wavelet coefficients is proposed, which make use of partial order, self - similarity between subbands of wavelet coefficients and the correlation of neighboring wavelet coefficients
受ezw 、 spiht 、 ebcot模型及3d - ezw 、 3d - spiht 、 3d - escot模型的啟發，本文綜合利用小波系數不同子帶間的自相似性、偏序性和同子帶內相鄰系數的相關性，提出了一種新的三維小波嵌入編碼上下文模型3d - pem 。 -
Since 3d - pcw tackles the coefficients as a whole, the context of a coefficient is computed only once, and the coefficient is encoded only once. but in 3d - escot the context has to be computed once and the coefficent has to be encoded once on every bit plane. therefore, 3d - pcw has much lower time complexity than 3d - escot
由於3d - pcw把系數作為一個整體進行編碼，每個系數只需要計算一次上下文，並編碼一次，而ebcot的擴展3d - escot每個系數在每個平面上都需要計算一次上下文並編碼一次，因而3d - pcw比3d - escot演算法的時間復雜度更低。
