阈值图像分割
I=imread('1.jpg');
I=double(I(:,:,1));
fxy=zeros(1,256);
[m,n]=size(I);
for i=1:m %统计每个灰度值的个数
for j=1:n
c=I(i,j);
fxy(c+1)=fxy(c+1)+1;
end
end
figure(1);plot(fxy);%画出灰度直方图
p1={'Input Num:'};
p2={'180'};
p3=inputdlg(p1,'Input Num:256',1,p2);
p=str2num(p3{1});
for i=1:m %小于阈值的为黑,大于阈值的为白
for j=1:n
if I(i,j)
