指纹的对比分析系统概述

毕业设计完成于2012年，现阶段关于图像的东西都是走神经网络了，本文仅可以作为背景知识和简单的课程设计参考,本文另附一个MFC演示程序与全套文档，见文末下载链接

摘要： 指纹识别技术作为生物识别技术中最为具有应用前景的技术之一，近年来取得了长足的发展，并广泛应用于各种场合。由于指纹所具有的唯一性和不变性，以及指纹识别技术具有很高的可行性和实用性，指纹识别成为目前最流行、最可靠的个人身份认证技术之一。所以对指纹识别技术的研究具有重要的理论和实际意义。
指纹识别的一般性过程分为三步：指纹图像的预处理，指纹特征提取以及特征匹配。本设计采用Visual Studio 2008 MFC依照软件开发自顶向下，逐步细化的经典模式，按上述步骤完成开发工作，成功实现了基于BMP格式指纹图像的增强，二值化，细化，特征提取以及对比分析工作。完成了具有一般性的指纹对比分析系统。

Abstract: The fingerprint identification technology act as the most promising application of biometric technologies, has made considerable development in recent years and is widely used in various occasions. Due to the uniqueness and invariability of fingerprints，the fingerprint recognition becomes the most popular and reliable personal authentication technology. As a consequence, the study of fingerprint identification technology is of great theoretical and practical significance.
Fingerprint identification can be divided into three periods: preprocessing of fingerprint images, feature extraction and feature matching In this design, we adopt the visual studio 2008 edition’s MFC, in accordance with software development which uses top-to-down process and the gradual refinement of the classic model , and successfully achieve enhancement ,binarization ,thinning of fingerprint image, based on the BMP format. Through the whole process, we finally complete a general fingerprint contrast and analysis system

Key words: Fingerprint identification; MFC; enhancement
