两个简单程序，一个是在空域和频域分别实现了两个矩阵的卷积。另一个程序主要是为了查看几个模板的空域及频域响应形式，方便理解(Two simple procedures, one is in the spatial and frequency domain is realized for the convolution of two matrices. Another program is mainly to see the airspace of several templates and frequency domain response form, to facilitate understanding)

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.
