子程序代码: function e=qiege(d) [m,n]=size(d);

top=1;bottom=m;left=1;right=n; %int while sum(d(top,:))==0&&top<=m top=top+1; end

while sum(d(bottom,:))==0&&bottom>1 bottom=bottom-1; end

while sum(d(:,left))==0&&left

while sum(d(:,right))==0&&right>=1 right=right-1; end dd=right-left; hh=bottom-top;

e=imcrop(d,[left top dd hh]); %返回图像的一个裁剪区域

function [word,result]=getword(d) word=[];flag=0;y1=8;y2=0.5; while flag==0 [m,n]=size(d); wide=0;

while sum(d(:,wide+1))~=0&&wide<=n-2 wide=wide+1;

end

temp=qiege(imcrop(d,[1 1 wide m])); [m1,n1]=size(temp); if widey2 d(:,[1:wide])=0; if sum(sum(d))~=0

d=qiege(d);%切割出最小范围 else word=[];flag=1; end else

word=qiege(imcrop(d,[1 1 wide m])); d(:,[1:wide])=0; if sum(sum(d))~=0 d=qiege(d);flag=1; else d=[]; end end end result=d;
