说明：  在光学系统中根据光学系统的孔径函数生成MTF曲线(n the optical system, the MTF curve is generated according to the aperture function of the optical system)

医学图像大部分都是dicom图像，这里提供dicom图像读取、显示和保存的matlab代码，以为医学图像处理初学者提供学习。 (Dicom medical images are mostly images, here to read dicom image, display, and save the matlab code, provided that the medical image processing for beginners to learn.)

本文介绍了一种测量大气能见度的方法，双亮度差法，代码中给出了详细的注释，并且包括OSTU方法等等(In this paper, a measuring method of atmospheric visibility double brightness difference method, the code is given detailed annotations, and including the OSTU method and so on)

基于KSVD算法的图像去噪算法，稀疏表示，字典学习，OMP算法，基于DCT字典的图像去噪，demo可以直接运行。(Image denoising by KSVD algorithm，spare representation，dictionary learning，OMP algorithm，DCT dictionary)

说明：  四种点云配准算法。FPFH,NDT,3DS…(Four point cloud registration algorithms.FPFH,NDT,3DS.)

图象的直方图处理及全尺度变换和各种性能指标的计算，如psnr,mse等(image histogram processing and full scale transformation and various performance indicators, such as psnr, mse etc.)

说明：  FPGA数字图像处理实现均值滤波，并且仿真将生成图片写出TXT格式以便使用MATLAB查看(Mean filter is realized by digital image processing in FPGA, and the generated image is written in TXT format for viewing with MATLAB.)

针对各类分数阶混沌系统进行同步，数值仿真结果证明系统的稳定性(Numerical simulations show that the system is stable for all kinds of fractional order chaotic systems.)

基于SUSAN特征检测算子的边缘提取，添加图片即可运行，可自行根据图片特征设置参数得到较好的边缘检测效果(Edge detection feature extraction SUSAN operator, add images to run, you can set your own parameters to get a better edge detection based on image characteristics)

说明：  用canny算子来检测图像边缘，VC++(Using canny operator to detect image edge)
