鉴于LCD方法存在的问题,本文提出了一种基于互相关匹配端点延拓局部特征尺度分解(Cross-correlation matching endpoint Extension Local Characteristic scale Decomposition,简称CELCD),由于LCD分解原理是依据信号的局部极值点信息不断进行筛分信号,在信号分解时需要先确定信号的局部极值点,而信号的两个端点可能不是极值点,因此在信号两端点就会出现虚假成分,且该现象随着分解的进行向数据内部扩散,产生端点效应,导致分解

本设计为基于MATLAB特征点匹配的指纹识别系统。带有一个GUI界面。主要对指纹图像进行三方面处理:图像预处理、特征提取和特征匹配。图像预处理包括四个步骤:图像分割、滤波增强、二值化、细化,对指纹图像进行预处理后,去除了原图像的冗余部分,方便后续的识别处理;特征提取主要是提取指纹图像细化后的端点和分叉点;特征匹配是利用两个指纹的图像进行特征点比较,来确定两幅图像是否来自于同一手指。(This design is a fingerprint recognition system based on
