Image Feature Extraction of Code

一个普通的小游戏，没有什么功能，就一个小小的游戏(An ordinary little game, no function, just a garbage game.)

说明：  实现matlab对感兴趣区域（ROI）提取(Implement MATLAB to extract ROI)

ENVI二次开发常用功能代码，包括大气校正、定标、分类(监督+非监督)、裁剪、镶嵌等(ENVI secondary development commonly used function codes, including atmospheric calibration, calibration, classification (supervision+ unsupervised), cutting, mosaic, etc.)

改进SIFT算法，用于光学图像和SAR图像配准(Improved SIFT methods for Registration of Optical and SAR image.)

利用Retinex中心环绕算法进行阴影去除，飞常详细并含有程序对应的PPT(Centers around the use of Retinex algorithm to remove the shadow, flying often detailed and contain procedures for the corresponding PPT)

说明：  利用非局部均值的算法对图像做去噪，速度比较快，但效果一般，存在一定局限性(Using non-local mean algorithm to denoise image is faster, but the effect is general and there are some limitations.)

说明：  基于matlab的傅里叶光学仿真教程和光学原理讲解，有很多实用代码(matlab tutorial for fourier optics, containing simulation codes and basic theory)

该程序可以对图像进行二值化处理，提取边缘点坐标。(The program can be two-valued image processing, extraction of the edge point coordinates.)

改进的 SUSAN 算法，用于自适应阈值的边缘检测(improved algorithm for the adaptive thresholding edge detection)

说明：  给定两张图片，利用ssim来计算两张图片他们之间的ssim相似度(compute ssim between two images)
