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. JPEG 2000 is often thought to be the future replace JPEG (based on the discrete cosine transform) is the next generation of image compression standard. The file JPEG 2000 vice file name is usually. 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 )

Mersenne Twister随机数发生器（Mersenne Twister generator,MTG for short）是Makoto Matsumoto于1998年对TGFSRG(旋转广义反馈移位寄存器发生器)的更进一步改进。(Mersenne Twister random number generator (Mersenne Twister generator, MTG for short) is Makoto Matsumoto in 1998 TGFSRG (rotation generalized feedback shift register generator) is further improved.)

样本熵在信号分析中有很重要的作用，其主要用来提取非线性特征，从而用于特征分析。(Sample entropy has a very important role in signal analysis, which is mainly used to extract the nonlinear characteristics for analysis.)

LU分解 用比较通俗易懂的语言编写了ＬＵ分解的相关程序(LU)

众多恒虚警检测（CFAR）算法都是基于单元平均（CA:Cell Avarage）的方法，该算法需要较大的运算量。本程序给出了基于有序统计（OS:Order Statistic）的CFAR检测算法，弥补了CA_CFAR检测算法的不足，同时还配有本人硕士毕业论文中的检测图像以及实验结果，具有一定的参考价值。(CA_CFAR algorithm often requires large computational complexity. OS_CFAR algorithm is presented, which can make up the disadvantages in CA_CFAR. In the meantime, some processed images are given, which has a high value of reference.)
