代码说明:

  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.)

    说明:  程序使用说明: 1、软件应用平台:Matlab6.5或更高; 2、打开方法: 将文件所在目录设为工作目录,然后打开wavlet.fig,在noise提示框下输入噪声强度,在0-0.1之间(不能为零)。 然后点process按钮,就会显示实验结果,包括原图像,加噪图像,去噪图像的对比以及当前的psnr值。 wavlet.m是程序文件。 程序内容写在在程序的注释里。 阈值的更改没有实现可视化,在源程序中可以改。(Procedure for use: 1, Software Platform: Matlab6.5 or higher 2, open the way: the file directory set the working directory, then open the wavlet.fig, the noise boxes, enter the noise level, in the 0-0.1 between (not zero). Then process the button, it will show the experimental results, including the original image, noise image denoising image contrast and the current psnr value. wavlet.m is the program file. Program content in the program notes written inside. Threshold changes are not visualized in the source program can be changed.)
