An Improved EZW Hyperspectral Image Compression被引量：2
《Journal of Computer and Communications》2014年第2期31-36,共6页Kai-Jen Cheng Jeffrey C. Dill 
The paper describes an efficient lossy and lossless three dimensional (3D) image compression of hyperspectral images. The method adopts the 3D spatial-spectral hybrid transform and the proposed transform-based coder. ...

现行的基于图像数据挖掘,主要采用聚类分析方法,但聚类分析方法的不足,是图像应该被划为几类受很多因子的影响,很难给出有说服力的证据及证明。本文针对此缺陷,提出了关于图像数据挖掘的一种新思想,即引入小波理论中的Zerotree算法来确...

Embedded coding of medical images with regions of interest based on 3-D zerotree
《Frontiers of Electrical and Electronic Engineering in China》2007年第1期8-12,共5页MA Jing WU Chengke CHEN Dong ZHOU Youxi 
supported by the National Natural Science Foundation of China(Grant No.60272050).
In order to satisfy the need of diagnoses,based on the characteristic of medical images that a sequence of frames are formed in one body inspection,a new strategy for medical images compression is proposed.The 3-D wav...
