matlab GUI指纹识别门禁系统介绍及源码实现

function varargout = zwsb2(varargin)
% ZWSB2 M-file for zwsb2.fig
%      ZWSB2, by itself, creates a new ZWSB2 or raises the existing
%      singleton*.
%
%      H = ZWSB2 returns the handle to a new ZWSB2 or the handle to
%      the existing singleton*.
%
%      ZWSB2('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in ZWSB2.M with the given input arguments.
%
%      ZWSB2('Property','Value',...) creates a new ZWSB2 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before zwsb2_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to zwsb2_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".

%⑤ 二值化图像及二值化后处理
f5 = imgbin (f4);
g5 = imgbin (g4);
%⑥ 图像细化
f6 = imgthi (f5);
g6 = imgthi (g5);
%⑦ 特征点提取
f7 = imgpoi (f6);

%⑧ 指纹特征比对 
R = imgcom (f7,g7);
%⑨ 计算两组样本特征点的相关系数
