图像置乱加密。 主要思想：从两幅图像中选取信息，然后置乱成一幅图像。(Image scrambling encryption. The main idea: to select information from two images, and then scrambling into an image.)

该资料为多目标粒子群求优MATLAB代码。改进的多目标粒子群算法，包括多个测试函数 对程序中的部分参数进行修改将更好地求解某些函数(The data is a multi object particle swarm optimization MATLAB code. The improved multi-objective particle swarm optimization algorithm, including the number of test functions in the program to modify some of the parameters will be better to solve certain functions)

加权最小二乘法.用matlab实现加权最小二乘法，采用封装函数的形式编写，易于使用。(Weighted least squares method. Using matlab realize the weighted least squares method, in the form of wrapper function written, easy to use.)

说明：  利用LSSVM对数据进行训练，然后可以进行分类和预测，包括LSSVM工具箱。(LSSVM is used to train the data, and then classification and prediction can be carried out, including the LSSVM toolbox.)
