CANNY算子的非极大值抑制步骤，使用插值计算，支持不同的抑制半径(Non-maxima suppression step CANNY Operators using interpolation, support different radii suppression)

MATLAB环境下编的人脸检测和识别算法，人脸识别部分采用的pca算法，另外包括一个人机界面，直接运行facedec程序即可运行(MATLAB environment, compiled by face detection and recognition algorithms, face recognition pca algorithm is used in some of the other, including a man-machine interface, programs can be run directly run the facedec)

使用IDL编程来实现打开BMP，TIFF，IMG，JPEG，PNG和其他图像，实现缩放，缩放，平移，图像增强，平滑，边缘检测(Using IDL programming bmp, tiff, img, jpeg, png and other images to achieve open and zoom in, zoom, pan, image enhancement, smoothing, edge detection)

基于离散小波变换和IHS变换的遥感图像融合代码，主要用于多光谱和全色图像的融合(matlab code for remote sensing image fusion based on DWT and IHS, mainly for mutilspectral and panchromatic image fusion)

说明：  短时傅里叶变换的一些简单的演示，其中有矩形窗和高斯窗(some demos for the short time fourier transform)

针对现有方法存在的隐藏容量低、操作不灵活的缺陷，文章提出了一种基于无损压缩的加密图像可逆 信息隐藏算法。(In view of the defects of low hiding capacity and inflexible operation of the existing methods, this paper proposes a reversible information hiding algorithm for encrypted images based on lossless compression.)

该文件夹包括基于邻阈的小波图像去噪程序。主程序为wave_neighbor.m，实现3*3和5*5邻域去噪；wov_win.m为函数m文件，实现3*3和5*5的滑动窗口；cacupsnr.m为函数m文件，计算mse和psnr等。(This is about image denoising with the method of wavelet.It includes 3×3 and 5×5 neighborhood window.)

利用DOA和TOA对运动辐射源的单舰无源定位(Using a single passive location DOA and TOA ship moving emitter)

说明：  首先对指纹图像进行预处理，包括图像的分割，增强，二值化，细化。对细化后的图像进行特征点的提取，最后通过细节特征匹配完成指纹的识别。(Firstly, the fingerprint image is preprocessed, including image segmentation, enhancement, binarization and thinning. The refined image is extracted by feature points, and the fingerprint recognition is completed by minutiae feature matching.)

说明：  这是HALCON自带的例程，名称全部汉化。将其中文件对应index_examples_en_US.xml替换，另外operators文件夹也替换掉。(This is the routine that comes with Halcon. All names are Chinese. Index the file_ examples_ En_ US.xml Replace. In addition, the operators folder is also replaced)
