基于人工神经元的指纹识别及自学习系统的研究与制作
摘  要

 本文档是一门目前被广泛应用的实用化技术，是一个不断面临挑战的研究热点。近年来国际模式识别学会组织的FVC（Fingerprint Verification Competition,国际指纹识别算法竞赛）吸引了更多的目光，反映了目前学术界与产业界对指纹识别技术的广泛认可，还越来越多的应用在银行、社保、门禁、考勤和公安司法等领域，正逐步走进人们的生活中，成为大家共同关注的话题。
 本文档从指纹识别起源、人体指纹的特征和指纹图像的采集处理各方面，详细介绍了只指纹识别技术的特点、指纹识别算法的基本原理和人工神经元在此方面的应用。
 人工神经网络(ARTIFICIAL NEURAL NETWORK，简称A.N.N.)是在对人脑组织结构和运行机智的认识理解基础之上模拟其结构和智能行为的一种工程系统。早在本世纪40年代初期，心理学家McCulloch、数学家Pitts就提出了人工神经网络的第一个数学模型，从此开创了神经科学理论的研究时代。其后，F.Rosenblatt、Widrow和Hopf、J.J.Hopfield等学者又先后提出了感知模型，使得人工神经网络技术得以蓬勃发展。

Fingerprint distinguishing in Man-made nerve net
Abstract
 
 This is a thesis about a trick extensive use now, is a face to the research heat of the challenge to order  the FVC( the Fingerprint Verification Competition, the international fingerprint identifies the calculate way contest) that the international mode identifies the academic association organization to draw on more visions in recent years, reflect the academic circles and the industry fields to identify the technical and extensive approbation to the fingerprint currently, return more and more applications to protect in the bank, agency, control at gate, depend frequently and public security official judicatory etc. realm, just walk into gradually in the people's life, become everyone the topic of the common concern.
 This thesis collects to handle the everyone to face from the characteristic and the fingerprint pictures that the fingerprint identifies the origins, the human body fingerprint, detailed introduced to query to identify the basic principle and the artificial nerve dollars that the technical characteristics, fingerprint identifies the calculate way in this aspect of application.
 The artificial nerve network"( the ARTIFICIAL NEURAL NETWORK, brief name A.N.N.) is at to person the brain organization structure and circulate the understanding comprehension foundation of the tactful on imitate a kind of engineering system of its structure and the intelligence behavior 40's in century initial stage, the psychologist McCulloch, the mathematician Pitts put forward the artificial nerve network the first piece learns the model, founding the research ages of the nerve science  from Afterward, the scholar, such as, F.Rosenblatt, Widrow and Hopfs, and J.J.Hopfield etc. puts forward the feeling to know the model successively again, can make the artificial nerve  network technique develop rapidly.
