说明：  这是Rafael C.Gonzalez(冈萨雷斯)的matlab英文版，是数字图像处理的经典教材(this is a book about the digital image process ,it is very classical.)

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.)

首先确认安卓手机硬件的蓝牙模块是否支持蓝牙4.0. （手机硬件模块不支持的话，软件做的在正确也连不上！） 2. 系统升级到4.3 或更新版本 3. 资料包内的 HMBLEComAssistant.rar 可用于测试 收发(AT+BAUD0 AT+NAMEAC AT+PASS000000 //必须输入满6位 AT+TYPE1 AT+ROLE0)

单高斯模型是检测运动目标有效方法，这是一种matlab实现。(Single Gaussian model is an effective way to detect moving targets, which is a matlab achieve.)

说明：  通过时域转换为频域，在频域中截取低频部分，去掉高频部分将结果再转换到时域以实现低通滤波的功能。(Through the time domain is converted to frequency domain, in the frequency domain low-frequency part of the interception, to remove high-frequency part of the results and then switch to the time domain in order to achieve low-pass filter function.)

介绍了简单的ldpc编码，对初学者很有用！(Introduced a simple ldpc code is useful for beginners!)

说明：  故障诊断的源码，基于matlab，包括时域频域，细化普，倒频谱等(Source of fault diagnosis, based on matlab, including time domain frequency domain, refine general, inverted spectrum)

PID控制是工业工程中经常应用的方法，也比较成熟，本例中给出了伺服PID控制的私募林肯仿真(PID control is often applied in industrial engineering, is more mature, in this case gives the servo PID control of the private Lincoln simulation)
