Block base DCT data hiding and recovery of secrete image.

This project has proposed an alternate novel method of finger vein and finger texture recognition system .This system has taken more advantage than the existing system in term of security purpose since the vein pattern is not visible to human vision without any special device, it will not produce any trace in any object. We examined a complete and fully automated approach for the identification of low-resolution finger surface / texture images for the performance improvement

附件是齿轮箱故障数据，txt格式文件，pdf格式的齿轮箱故障数据介绍，和word关于齿轮箱故障的知识详解，对研究旋转机械故障诊断的朋友有帮助(the attachment is the fault data of gear box in txt documents, and data instruction in pdf document. Also, the detailed intruction of gear box is in word documents.)

基于matlab的人脸识别，不包含图像库，使用PCA分析方法(Matlab-based face recognition, image database does not include the use of PCA analysis)

实现ID3算法，在结果中以树表示出来。决策树是对数据进行分类，以此达到预测的目的。该决策树方法先根据训练集数据形成决策树，如果该树不能对所有对象给出正确的分类，那么选择一些例外加入到训练集数据中，重复该过程一直到形成正确的决策集。(ID3 algorithm to achieve, in the results that come out to the tree. Decision tree is to classify the data, thus achieving the purpose of prediction. The decision tree training set of data according to the formation of the first decision tree, if the tree can not give the correct classification of all objects, then select a number of exceptions to the training set data, repeat the process until the correct decision set.)

Creates a 3D look table for a given size and width

《MATLAB信号处理》刘波著 电子版以及全部的源代码，非常合适初学者(MATLAB signal processing _ liu electronic as well as all the source code, very suitable for beginners)

有效观察OAM的相位模式，可自由设定拓扑荷数(Observing the phase mode of OAM effectively, the topological charge can be set freely.)

some code on matlab,previous code type

说明：  一个BP神经网络训练的源代码 其中算法部分并未用到MATLAB中的训练函数，可以加深对BP的理解(A BP neural network training algorithm in which the source code was not used in the training function in MATLAB, you can deepen their understanding of BP)
