Matlab实现人民币币值的显示 实现代码

上图像和程序了……记得程序好像是很久以前收藏的了……分享出来了……

clear all;clc;
Img = imread('I.jpg');
if ndims(Img)==3
I=rgb2gray(Img);
else
I=Img;
end

imshow(bw);title('初始二值图像');
bw(1:round(1/4*size(bw,1)),:)=0;

figure,imshow(bw);title('只含有数字区域');
L=bwlabel(bw);

[ar,ind]=sort(Ar,'descend');
bw1=bw;bw2=bw;bw3=bw;
