在 MATLAB Online 中打开

I = imread('your image');   % read image 
Ibw = im2bw(I);            
Ilabel = bwlabel(Ibw);   
stat = regionprops(Ilabel,'centroid');   % get centroid 
imshow(I); hold on;
plot(stat.Centroid(1),stat.Centroid(2),'ro');
%%dive the image 
c = fix(stat.Centroid) ;
I1 = I(1:c(1),:,:) ;
I2 = I(c(1)+1:end,:,:) ;
figure ; imshow(I1) ; 
figure ; imshow(I2) ;
