一个MATLAB GUI程序，可以方便地用来手动标记正训练样本和负训练样本。 —————————————————— 1.首先输入要标定的数据库目录、要存放正训练样本的目录、要存放负训练样本的目录 2.点击“开始”，程序自动依次显示数据库目录中的图片 3.点击“正例”或“反例”将会把当前图片复制到相应目录 4.可以在图片上点击拖动圈出一个区域，以截取圈出的区域作为样本 5.选中“约束选取比例”可以使得最终选取的样本有固定的大小(A matlab GUI program that can be used to label training samples manually. It contains rich functions)

In this paper we present the usefulness of the algorithm DCT (Discrete cosine Transform) blocks applied level image compression JPEG (Joint Photographic Experts Goup). It has been shown that this algorithm is the most efficient in the case of compression because it has very good properties for compaction energy related values. As a basic principle we eliminate high frequencies and keep the low and medium without visibly affecting image. DCT in JPEG compression algorithm is encountered in practical applications such as face detection, skin color, facial recognition, iris, fingerprints

本程序为带遗忘因子的递归最小二乘的程序，在MATLAB下进行仿真。(This procedure with forgetting factor recursive least squares procedure, the MATLAB simulation.)

该模糊控制器的特点是针对大延迟或纯滞后系统(加干扰)进行控制，利用matlab自带fuzzy工具箱，采用经典文献中的模糊控制规则，并附原理及效果图以供学习交流。(The fuzzy controller is characterized by delayed or for large time delay system (plus interference) control, using fuzzy toolbox matlab own, using the classical literature of fuzzy control rules, together with the principle and effect diagram for the exchange of learning.)

绘制庞加莱截面图 在相空间中适当（要有利于观察系统的运动特征和变化，如截面不能与轨线相切，更不能包含轨线）选取一截面，在此截面上某一对共轭变量如x1和x.1取固定值，称此截面为Poincare截面，相空间的连续轨迹与Poincare截面的交点成为截点。(Poincare mapping sections in the phase space properly (should be beneficial to observe the system and changes in movement characteristics, such as the cross-section can not be tangent trajectory, but also can not contain rail line) to select a cross-section, in this section for a total of conjugate variables, such as x1 and X.1 take a fixed value, call this cross-section for the Poincare section, the phase space of the continuous trajectory of the point of intersection with the Poincare cross-section to become cut-off point.)
