usps数据库为标准手写数据库，此为mat数据文件，含训练集和测试(USPS database is a standard handwritten database, which is a mat data file, including training set and test)

深度搜索算法用于一幅二值图像，指定开始点和目标点(deep first search method is used for binary image,with assigned start and end point)

对高光谱图像进行主成分分析，提取其中的主要信息(Hyperspectral images of the principal component analysis, extracting one of the main information)

浏览图片的缩略图时，点击某张缩略图，被点击的缩略图会在当前视图放大并且全屏显示，背景用黑色透明视图遮挡。再次点击图片，将回到缩略图浏览状态(Media Focus Manager)

harris角点检测算法，代码可以通过修改sigma, thresh, radius, disp的值控制角点数量。(harris corner detection algorithm, the code can be by modifying the sigma, thresh, radius, disp corner of the value of quantity control.)

1、运动目标进行检测与跟踪，背景差分法，卡尔曼滤波，检测结果用红色外接矩形框表示，跟踪结果用绿色矩形框表示 2、采用平均背景法更新背景图像； 3、代码部分附详细解释(1. The moving target in the video sequence is detected and tracked, the moving target detection part uses the background difference method, the tracking part uses Calman filter, the detection result is represented by the red outer rectangle frame, and the tracking result is expressed in green rectangle frame. 2. The background image is updated with the average background method. 3. The part of the code is explained in detail)

vtk、itk、tcl/tk联合开发教程。(vtk, itk, tcl/tk Joint Development Guide.)

说明：  使用中值，均值，小波，DCT，PCA五种方法实现对图像的去噪处理。(Five methods, median, mean, wavelet, DCT and PCA, are used to denoise the image.)

图像经过双随机处理和分数阶傅里叶变换，可以达到加密解密的功能，且对密钥敏感性较强。(The image undergoes double random processing and fractional Fourier transform, which can achieve the function of encryption and decryption, and has strong sensitivity to the key.)

这是一个摄影测量的前方交会程序，根据给定的（也课自己算出）内外定向参数，课求出地面点的三位坐标(This is a forward intersection photogrammetry procedures, according to a given (also class their calculated) internal and external orientation parameters, derived classes of the three coordinates of ground points)
