实验思路
先对原图进行几何变化(旋转)变成长方形,再对图像进行分割
实验代码
clear
clc
init=imread('C:\Users\joczu\Desktop\作业3.bmp');
%图像旋转
G=rgb2gray(init);
E=edge(G);
theta=1:180;
[R,xp]=radon(E,theta);
[E,J]=find(R>=max(max(R)));
Q=90-J;
I=imrotate(G,Q,'bilinear','crop');
%图像切割
s=I(:,:,1);
bw=im2bw(s,graythresh(s)); %graythresh自动找比较合适的阈值
se=strel('disk',1); %创建切割形状
bw2=imclose(bw,se);
figure(1);
imshow(bw2);
perim=bwperim(bw2,8); %表示从输入图像BW1中返回只包括对象边缘坐标
r=I(:,:,1);
%g=I(:,:,2);
%b=I(:,:,3);
r(perim)=250;
%g(perim)=0;
%b(perim)=0;
I(:,:,1)=r;
%I(:,:,2)=g;
%I(:,:,3)=b;
figure(2);
imshow(I);
