matlab指纹匹配

不怎么实用，希望各位批评指导，相互学习 clear all,close all, TestDatabasePath = uigetdir('E:\我的大学', 'Select test database path');%自己设置地址 prompt = {'Enter test image name:'}; dlg_title = 'finger Recognition System'; num_lines= 1; def = {'1'}; TestImage = inputdlg(prompt,dlg_title,num_lines,def); TestImage = strcat(TestDatabasePath,'\',char(TestImage),'.bmp'); im = imread(TestImage); tic I=imresize(im,[200 200]); figure(1),subplot(131),imshow(I),title('原图'); set(gcf,'position',[1 1 600 600]); level=graythresh(I); J=im2bw(I,level); figure(1),subplot(132),imshow(J),title('二值图');
