matlab在数字图象处理中有着自己独特的优势，本文主要介绍其在数字图象处理中的强大的作用和使用方法。(matlab in digital image processing has its own unique advantages, this paper introduce its digital image processing in a powerful role and use.)

席位分配 可以在准备数学建模的时候作为练习资料(mathmodeling)

基于levelset的测地活动轮廓 matlab源码，可实现多目标轮廓的 提取。对噪声图象具有良好的鲁棒性。但是计算量较大，耗时过多(levelset based on the geodesic active contour Matlab source, more achievable goal contour extraction. Image noise is a good robust. However, the large amount of calculation, time-consuming excessive)

Abstract- Although the vast majority of EMV payments are processed without a hitch, there are occasions when the cardholder later repudiates a payment. The cardholder may be adamant that he or she was not present to authorize the transaction, but the issuing bank considers the transaction data and certificate to evidence otherwise because they show that the chip and PIN mechanism had been used to authenticate the cardholder. A solution is proposed that leaves a cryptographic mark on the card’s chip which could help determine whether or not that card was present for the transaction and thereby help adjudication.

说明：  本程序给出了最小二乘滤波算法的具体编程，程序中分析比较了自相关算法、协方差算法、前后向加窗算法的滤波效果(This procedure gives the least squares filtering algorithm specific programming, program analysis and comparison of the auto-correlation algorithm, covariance method, before and after windowing algorithm to the filtering effect)

matlab时频分析工具箱，包括各种时频分析函数(matlab time-frequency analysis toolbox, including a variety of time-frequency analysis functions)

说明：  希尔伯特黄变换，用EMD将信号分解成本征模态函数，对分解的IMF分量进行hilbert变换(Hilbert Huang transform (HHT), EMD is used to decompose the signal into the cost eigenmode function, and the decomposed IMF component is transformed by Hilbert transform)

implementation of copy move forgery detection based on ad hoc algorithm

说明：  广义互相关测信号时延的matlab代码，采用TDOA方法，其中延时计算采用GCC方法(Matlab code for time delay measurement of generalized cross-correlation signals)

OFDM信号的导频的插入包含LS,LMMSE,线性插值等(OFDM pilot signal insertion include LS, LMMSE, linear interpolation)
