很好的图像分割软件，内有全部源码，对研究matlab图像识别处理很有帮助(good image segmentation software, comprising all the source code, the study Matlab image recognition processing helpful)

说明：  可以对光谱数据进行预处理，除了偏最小二乘法之外，也有一些其他方法(Besides the partial least square method, there are also some other methods)

编程实现大津（Otsu）自动灰度阈值分割算法的程序(Programming (Otsu) automatic gray Otsu threshold segmentation algorithm)

C#模拟播放连续的图片为GIF动画，模拟出播放GIF的动画效果，在Debug/bin目录下，有很多的图像文件，有VS的可重新修改源码，适合学习，源码简单。(C# analog playback consecutive pictures as an animated GIF, animated GIF to simulate the effect of playing in Debug/bin directory, there are a lot of image files, there VS can re-edit the source code, suitable for learning, simple source.)

说明：  出一个基于扩散与位平面Amold映射相结合的彩色图像置乱，以及采用Chen系统产 生的混沌序列加密的图像加密算法。(A combination of diffusion bit plane Amold mapping based color image scrambling, and Chen system chaotic sequence encryption image encryption algorithm.)

该程序主要实现图像的无损压缩，具体算法包括： （1）整数小波变换＋SPIHT无损压缩 其中整数小波可以采用JPEG2000提供的5－3小波，也可以采用S＋P变换，本程序均已给出。 （2）DPCM＋算术编码 DPCM采用的是JPEG中采用的方法； （3）JPEG－LS标准 JPEG－LS的无损压缩性能非常好，超过JPEG2000。(The program mainly realize lossless image compression, the specific algorithm include: (1) integer wavelet transform SPIHT Integer Wavelet lossless compression which can be used to provide the 5-3 wavelet JPEG2000, can also adopt the S P transform, the procedures are given. (2) DPCM arithmetic coding DPCM is used in JPEG methodology (3) JPEG-LS standard JPEG-LS lossless compression of very good performance, more than JPEG2000.)

分三种类型实现分水岭算法：一般分水岭分割、使用梯度的两次分水岭分割、使用梯度加掩模的三次分水岭算法(Realize three types of sub-watershed algorithm: a general watershed segmentation, the use of two gradient watershed segmentation, the use of gradient mask plus three watershed algorithm)

利用Artoolkit实现了虚拟现实的算法，VS2008下测试通过(Use Artoolkit algorithm to achieve a virtual reality, VS2008 under test)

读取RAW格式文件，将其转换为BMP格式文件并存储(raw 2 bmp file format convert)

说明：  求lena图像的信息熵，图像大小为256X256(For lena image information entropy, image size is 256x256)
