包括常用的IHS,PCA 加权图像融合三种算法的Matlab源代码(Which are used in the IHS, PCA-weighted Image Fusion Algorithm three Matlab source code)

对于空间两个点云，利用经典的icp算法进行匹配(ICP fit points in data to the points in model. Fit with respect to minimize the sum of square errors with the closest model points and data points. )

以python语言为平台，对机载激光雷达原始数据Las格式和txt格式进行读取，并根据信息熵确定维度特征计算的最佳邻域半径，最后计算得到最佳邻域半径和最佳维度特征值(Based on Python language, the Las format and TXT format of airborne lidar raw data are read, and the optimal neighborhood radius is determined according to the information entropy. Finally, the optimal neighborhood radius and the optimal dimension eigenvalue are calculated.)

JSteg隐写技术matlab实现代码--基本思想：用秘密信息比特直接替换JPEG图像中量化后DCT系数的最低比特位，但若量化后DCT系数为0或者1，则不进行处理。（DCT系数的LSB嵌入） (JSteg steganography matlab code- the basic idea: direct replacement with the secret information bits JPEG image quantized DCT coefficients in the least significant bit, but if the quantized DCT coefficient is 0 or 1, no processing. (DCT coefficients LSB embedding))

About a com application 关于一个com的应用(The Application of About a com application to a com)

shanChen两相流LBM的c版源代码，参考shanChen.m修改的，希望对不太熟悉Matlab的有所帮助(c code of liquid-liquid flow of shanchen)

说明：  使用python实现图像的加解密算法，涉及到基于RC4的图像加解密，基于logistic的图像加解密，arnold图像置换，有图像界面，使用QT制作(Using Python to implement image encryption and decryption algorithm involves image encryption and decryption based on RC4, image encryption and decryption based on logistic, Arnold image replacement, image interface, QT production)

说明：  这个文件中包含了三种图像相似度的计算方法，分别是灰度分布计算方法、颜色分布直方图计算方法、还有结构相似度SSIM计算方法。(This file contains three image similarity calculation methods, namely, gray distribution calculation method, color distribution histogram calculation method, and structure similarity SSIM calculation method.)
