车牌定位参考程序 滤波 h=fspecial('average',3); d=im2bw(round(filter2(h,d))); % 膨胀或腐蚀 se=eye(2); [m,n]=size(d); if bwarea(d)/m/n>=0.365 d=imerode(d,se); elseif bwarea(d)/m/n<=0.235 d=imdilate(d,se); end imwrite(d,'5.膨胀或腐蚀处理后.jpg'); figure(8),subplot(3,2,

function e=qiege(d) [m,n]=size(d); top=1; bottom=m; left=1; right=n; while sum(d(top,:))==0&⊤1 bottom=bottom-1; end while sum(d(:,left))==0&&left;=1 right=right-1; end dd=right-left; hh=bottom-top; e=imcrop(d,[left top dd hh]);

matlab的qiege子程序，用于车牌字符分割上，存入工作路径，
