说明：  提取视频中的图片，每一帧的信息，把视频分为图片信息(get picture of video)

用matlab编程实现的POCS-TVM算法，重建了一幅大小180*180的Shepp-Logan头部模型图像，探测器个数260，投影角度为均匀发布在0-180度之间的60个角度。(The POCS-TVM algorithm based on MATLAB programming is used to reconstruct a Shepp-Logan head image with a size of 180*180. The number of detectors is 260, and the projection angle is 60 angles that are evenly distributed between 0-180 degrees.)

多个图片定时轮流切换，切换时可以改变样式(Photos regular rotation than switch can be changed when switching style)

函数visreg能够自动处理两幅对准图像的大小以及像素等细节问题，从而半透明地在另一幅图像上显示一幅图像。(Function visreg can automatically deal with the size of two aligned images and details such as pixels, thus displaying an image in another image in a semitransparent way.)

可以计算图像结构相似性，评价图像质量(Similarity of image structure can be calculated and image quality can be evaluated)

各种数字水印的嵌入和提取 检测和攻击 包括lsb 和dct等算法(A variety of digital watermark embedding and extraction, including detection and attack, such as algorithm lsb and dct)

说明：  实现脉搏波信号心率变异性分析,时域分析，频域分析和非线性分析(HRV analysis of the PPG signals)

一个很好的图像处理程序(a good image-processing program)

说明：  裁剪shape文件，使用idl编程实现，就是一个功能，编译以后可以直接调用这个函数(Clipping shape file, using idl programming, is a function, after compiling can directly call this function)

该程序是帧差法和背景法相结合的一种方法，非常新颖(The program is the frame difference method and the background of a combined approach, a very novel)
