How to divide an image into upper and lower regions and get those into separate variables, based on the centroid point, so that i need to compute the area, separately.

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) ;
