利用随机序列进行间隔控制，选择消息隐藏位(Intervals using random sequence control, select the message hidden bits)

This is a very helpful toolkit for matlab beginners. It includes algorithm for pattern classification, as well as image processing.

转换色彩空间，实现各种图像的Compress-Decompress(Color space conversion, to achieve a variety of image Compress-Decompress)

matlab优化工具箱函数的简单介绍，很全(matlab optimization the toolbox function of brief, very full)

老外写的压缩传感算法（CS），还是不错的，供大家学习(Foreigner writing compressed sensing algorithm (CS), is good for everyone to learn)

将源码保存为.m文件，程序生成logR/S，在matlab中循环调用这个文件，生成多个不同时间尺度的logR/S，然后求出logR/S与logN的直线斜率即是Hurst。(Will be saved as a source. M documents, procedures to generate logR/S, in the cycle of calling matlab in this document, to generate a number of different time scales of logR/S, and then calculated logR/S and the linear slope of logn is Hurst.)

利用music算法进行谱峰搜索，对一模拟信号的空间谱的峰值进行搜索(spectral-peak-searching music matlab)

和自回归模型一起写的小波模型，里面用到了自回归，自回归模型已上传(Since the regression model and the wavelet model with writing, which used the autoregressive, autoregressive models have been uploaded)

JPEG 2000是基于小波变换的图像压缩标准，由Joint Photographic Experts Group组织创建和维护。JPEG 2000通常被认为是未来取代JPEG（基于离散余弦变换）的下一代图像压缩标准。JPEG 2000文件的副档名通常为.jp2，MIME类型是image/jp2。 JPEG 2000的压缩比更高，而且不会产生原先的基于离散余弦变换的JPEG标准产生的块状模糊瑕疵。JPEG 2000同时支持有损数据压缩和无损数据压缩。另外，JPEG 2000也支持更复杂的渐进式显示和下载。 JPEG 2000是国际标准化组织（ISO）发布的标准，文档代码为ISO/IEC 15444-1：2000。虽然JPEG 2000在技术上有一定的优势，但是到目前为止（2006年），互联网上采用JPEG 2000技术制作的图像文件数量仍然很少，并且大多数的浏览器仍然不支持JPEG 2000图像文件的显示。但是，由于JPEG 2000在无损压缩下仍然能有比较好的压缩率，所以JPEG 2000在图像品质要求比较高的医学图像的分析和处理中已经有了一定程度的广泛应用。 (JPEG 2000 is based on wavelet transform the image compression standard, by Joint Photographic Experts Group organization to create and maintain.

Jp2, MIME type is image/jp2. JPEG 2000 compression ratio are higher, but won t produce the original based on discrete cosine transform JPEG standard of produce massive fuzzy flaws. JPEG 2000 also detrimental to support data compression and nondestructive data compression. In addition, JPEG 2000 also support more complex gradual display and download. JPEG 2000 is international organization for standardization (ISO) issued the standard, the document code for ISO/IEC 15444-1:2000. Although JPEG 2000 on the technology has certain advantages, but so far (2006), the Internet using JPEG 2000 technical production image file number still few, and most )
