用于Intravascular Photoacoustic 成像的源程序，采用Delay and Sum　算法编成。用于光声成像图形重构。(Used for Intravascular Photoacsoustic Imaging reconstruction based on Delay and sum algorithm.)

基于颜色衰减先验的图像去雾算法源码,作者是Zhu，大家可以作为论文中的比较算法(the matlab code of image dehazing based on color attenuation prior)

地图代数距离变换，八边形距离变换，马哈顿距离变换(Map algebra distance transform, eight sided distance transform, distance transformation)

说明：  几个白平衡程序，都能运行出来，可以用于水下图像偏绿偏蓝现象的颜色调整(Several white balance programs can be run)

图像处理的指针式仪表识别，利用OPENCV库，MFC对话框程序(Image processing pointer instrument identification, the OPENCV libraries, MFC dialog program)

说明：  运行程序，得到不同伽马因子给图像的整体明暗程度带来的变化(Run the program to get the change of the overall brightness of the image with different gamma factors)

一种基于non-sample的纹理合成demo，程序性能还有待优化，效果还不错.(texture synthesis demo.)

我的毕业设计，用matlab编的关键帧提取的代码，参考了光流法的代码。是基于帧差的欧式距离，均值，方差，差异系数下的关键帧提取。代码调试通过，运行结果理想，与大家分享下。(I graduated from design, matlab key frame extraction for the code, with reference to code optical flow method. Frame difference is based on the Euclidean distance, the mean, variance, difference coefficient under the key frame extraction. Debugging through the code, run the results are satisfactory, the next to share with you.)

视频水印matlab源码，此为第二个压缩包，在水印领域的爱好者可以下载作为参考(Video Watermarking Matlab source, which is the second-compressed, Watermark in the field of lovers can download as a reference)

压缩感知CS——采用小波变换进行稀疏表示，高斯随机矩阵为观测矩阵，重构算法为SP算法，对256*256的lena图处理，比较原图和SP算法在不同采样比例(0.74、0.5、0.3)下的重构效果，并各运行50次，比较算法性能PSNR和每次的运行时间(Compressed sensing CS- using wavelet transform as sparse representation, Gaussian random matrix as the observation matrix and SP algorithm as the reconstruction algorithm. Compare lena figure and the reconstruction results using SP algorithm at different sampling ratio (0.74,0.50.3),then each runs 50 times, compare the performance of PSNR and each running time)
