sgfilter

帅选出人体,yolo人员检测，yolo模型，并识别(peole detect and get the pix point of it ,)

利用高斯混合模型进行视频前景运动目标的提取！请使用自己的AVI文件。(extract the foreground moving object using the Gaussian mixture model)

说明：  图像识别的matlab程序实现，基于神经网络的图像识别(Image recognition matlab program implementation, image recognition based on neural networks)

应用到了操作系统界面功能支持库和图像格式转换支持库，在截取窗口位置时调用了API函数，大家做屏幕截图时可以参考下本例程中的代码。(Applied to the operating system interface features support libraries and image format conversion support library , in the interception of the window position API function calls , you can refer to the code in this routine when we do screenshots .)

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)

说明：  采用双相位编码对图像进行加密解密，采用双随机相位加密技术得到的 S 分量的相息图, 在加密的过 程中引进了随机相位因子, 在不知密钥的情况下解 密出 S 分量几乎不可能, 从而保证了的安全性(Two phase encoding is used to encrypt and decrypt the image)

说明：  选择一张灰度图片，添加高斯噪声并进行双边滤波(Select a gray image, add Gaussian noise and perform bilateral filtering)

基于小波的去噪算法，采用BAYES原理选取阈值，源代码，参考文献：Adaptive Wavelet Thresholding for Image Denoising and Compression(Wavelet-based denoising algorithm using the principle to select threshold BAYES, source code references: Adaptive Wavelet Thresholding for Image Denoisingand Compression)

image processing code for Histogram

说明：  地形分块下的匹配导航算法仿真程序，算法包括最优分块算法和匹配定位算法的仿真(Simulation program of matching navigation algorithm under terrain block, including the simulation of optimal block algorithm and matching positioning algorithm)
