Obscurance Invariance in Template Matching

介绍了一种用Matlab 信号处理工具箱进行数字滤波器设计的方法。给出了工具箱中的FDATool 图形用户接 口的详细使用方法,用FDATool 进行滤波器设计,可以随时对比设计要求和滤波器特性调整参数,直观简便,在每次改变参 数时,由于计算机的超强运算能力,只需点击设计按钮,新的滤波器立即产生,避免了传统滤波器设计的大量手工运算。并 用他设计出了满足性能要求的低通数字滤波器,实现了对加速度传感器干扰振动信号的滤除,解决了工程实际问题。(This thesis int roduces a digital filter designing method using signal processing toolbox in Matlab sof tware. It gives detailedly using specifications of FDATool graphical user interface ,when designing filter using FDATool ,you can com2 pare filter designing demand with filter character so as to adjust the parameter at any moment . For powerful operation function of the computer ,when the parameters are changed ,you only need point the design button ,new filter will be produced. In this way ,a mass of manual operation will be avoided. A good lowpass digital filter is designed using FDATool ,the filter can filter preferably the acceleration sensor vibration signal and resolve the engineering problem.)

matlab一些典型例程，供初学者使用，互相学习啊，(Matlab some of the typical routines for beginners, learn from each other,)

用于运动捕获数据的降维，可以提取极值点，进行关键帧提取或运动分割(Dimensionality reduction for motion capture data can be extracted extreme points, keyframe extraction or motion segmentation)

用vi传输矩阵法研究均匀布拉格光栅的传输特性(Uniform Bragg grating transmission characteristics of the transfer matrix method with vi)

说明：  此代码是用matlab软件仿真PAM4信号的传输，自动生成传输数据，在接收端做基本的信号处理，计算出误码率。(This code uses MATLAB software to simulate the transmission of pam4 signal, automatically generate the transmission data, do basic signal processing at the receiving end, and calculate the bit error rate.)

This code is a complete fingerprint core point detection. It uses orientation field for singular point detection and Zhang-suen algo. for thinning in preprocessing part

说明：  实现txt文本中的换行转换，具体是将第二行的文字放到第一行后面(Achieve txt convert text wrap)

使用BP算法实现压缩感知信号重构,需要已知观测空间基矩阵和观测向量(BP_Simplex,BP with a Simplex mplementation)

给出了很多matlab编程的具体例子，希望对大家编程有所帮助(it gives many examples about matlab program,and I hope this can help somebody)
