,对掌纹图像去噪主要采用低通滤波方法或邻域平均滤波方法,这两种方法可以有效地抑制噪声,但同时也滤除了一些边缘信息,而且还会发生一定程度的边缘模糊现象。因此这两种方法适合于提取掌纹中的主线(掌纹中最粗最长的若干条)特征,而不适合于需要保留更多边缘信息的特征提取。小波变换是目前比较流行的一种信号处理方法。-Palmprint image denoising using low-pass filtering method or the neighborhood average filter metho

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
