JPEG-2000-
本文所做的主要工作为:研究了JPEG2000标准的原理和基本框架,对JPEG 2000标准的核心—小波变换压缩技术进行了分析研究,概要的介绍了小波理论。对EZW算法进行了详细分析和描述,包括零树的含义、结构及其扫描方法。并应用Matlab图像处理工具箱和小波分析工具箱对图像小波变换处理,并通过接口工具Mex实现在Matlab环境下对C程序EZW编码的调用,实现了应用零树小波编码算法对图像的压缩处理,简单地实现了对JPEG 2000的仿真。(The main work that this text do is:Studied the principle and basic frames of the JPEG2000 standard, to the center of JPEG 2000- Wavelet transform compress which had been analyzed and researched .Carried on the detailed analysis and descriptions to the calculate way of EZW, include zero-tree coding, structures and it’s scans method. In Turbo C environment using C language to simulate wavelet zero-tree coding algorithm, using Matlab image processing toolbox and wavelet analysis toolbox, and using interface tool Mex to implement transferring the C program in Matlab, and implement the image compress by wavelet zero-tree transform coding methodology,and supplely implement JPEG2000.)

mincut
An implementation of "A min cut algorithm" by Stoer and Wagner.
In addition there is an option to find the minimal cut that does not separate a set of vertices.
This is not a mincut-maxflow algorithm.
