将图片等分成若干张分图

original_image=imread('429.jpg');
f=rgb2gray(original_image); %三通道转换成灰度图
figure(1);
imshow(f);
[m,n]=size(f);
p1=floor(m/3);
p2=floor(n/3);    


 fig1=f(1:p1,1:p2);
 figure(2);
 imshow(fig1);


fig2=f(1:p1,p2+1:2*p2);
figure(3);
imshow(fig2);


fig3=f(1:p1,2*p2+1:3*p2);
figure(4);
imshow(fig3);


fig4=f(p1+1:2*p1,1:p2);
figure(5);
imshow(fig4);


fig5=f(p1+1:2*p1,p2+1:2*p2);
figure(6);
imshow(fig5);


fig6=f(p1+1:2*p1,2*p2+1:3*p2);
figure(7);
imshow(fig6);


fig7=f(2*p1+1:3*p1,1:p2);

fig8=f(2*p1+1:3*p1,p2+1:2*p2);
figure(9);
imshow(fig8);


fig9=f(2*p1+1:3*p1,2*p2+1:3*p2);
figure(10);
imshow(fig9);
