SPCA The SPCA algorithm for computing sparse principal components.

说明：  平台基于visual studio2015，使用opencv函数实现中值滤波，进行图像处理(median blur based on opencv)

将颜色图像的色彩迁移到灰度图像中，采用的算法为welsh算法，有较好的效果；该程序是在VC++6.0的环境下调试实现的，能将颜色图像的颜色较好的迁移到灰度图像中.(Migration of the color image to gray image in color, using the algorithm for the welsh algorithm, better results the program in VC++6.0 environment debugging to achieve, can color the better the color of the image transfer to the gray image.)

通过利用自动阈值法，获得图像中颗粒粒径的分布，并将粒径分布进行排序。(By using automatic threshold method to obtain the particle size distribution of the image, and the particle size distribution of the sort.)

说明：  边缘检测技术用于医学图像的边缘检测， 对特定目标分割前做边缘定位(objective edge detectiong for medical AI platform.)

基于混沌理论和量化方法实现一种针对灰度图像的鲁棒水印算法。(Based on chaos theory and quantitative methods to achieve a robust watermarking algorithm for grayscale images.)

用于实现基于压缩感知在傅里叶系数域上的图像融合(For image fusion based on compressed sensing in the domain of Fourier coefficients)

说明：  本课题为基于MATLAB的小波变换dwt和离散余弦dct的多方法对比数字水印系统。带GUI交互界面。有一个主界面GUI，可以调用dwt方法的子界面和dct方法的子界面。流程包括，读取宿主图像和水印图像，嵌入，多种方法的攻击（剪切，加噪，旋转等），提取，最后利用psnr峰值信噪比进行评价不同攻击下，鲁棒性的好坏。(This project is based on MATLAB wavelet transform DWT and discrete cosine DCT multi method contrast digital watermarking system. With GUI interactive interface. There is a main interface GUI, which can call the sub interfaces of DWT method and DCT method. The process includes: reading host image and watermark image, embedding, attacks of various methods (cutting, adding noise, rotation, etc.), extracting. Finally, PSNR peak signal-to-noise ratio is used to evaluate the robustness of different attacks.)

实现两幅图像匹配。应用SSD+SAD+NCC算法的匹配，很好用的程序(Realizing Two Image Matching.Application of SSD+SAD+NCC algorithm matching, very useful program)

对于vc++中经典的画线画图示例程序.对于类的控制和画线算法的实现.代码简洁明了(For vc++ in a classic example of procedures for drawing a line drawing. The type of control and painting line algorithm. Concise code)
