说明：  matlab时针程序，能实现双时针的配合旋转，历时24小时(The matlab clockwise procedures to achieve dual-clockwise with the rotation, which lasted 24 hours)

基于matlab的一种图片加密算法，针对*.jpg格式的图片，稍加修改亦可以加密.png/.bmp等各种类型的图片。(a kind of encryption dealing with pictures in format .jpg based on matlab.)

说明：  BP_Adaboost模型即把BP神经网络作为弱分类器，反复训练BP神经网络预测样本输出，通过Adaboost算法得到多个BP神经网络弱分类器组成的强分类器，利用此方法设计出强分类器。(The BP_Adaboost model uses the BP neural network as a weak classifier, repeatedly trains the BP neural network to predict the sample output, and uses the Adaboost algorithm to obtain a strong classifier composed of multiple BP neural network weak classifiers. This method is used to design a strong classifier.)
