here there is the code i used where x is the original Image
bbox1=x(1:size(x,1)/4,1:size(x,2)/2,:);
var1=var(double(bbox1))
%%2
bbox2=x(size(x,1)/4+1:size(x,1)/2,1:size(x,2)/2,:);
var2=var(double(bbox2))
%%3
bbox3=x(size(x,1)/2:size(x,1)/3,1:size(x,2)/2,:);
var3=var(double(bbox3))
%%4
bbox4=x((size(x,1)/3)+1:size(x,1),1:size(x,2)/2,:);
var4=var(double(bbox4))
%%5
bbox5=x(1:size(x,1)/4,size(x,2)/2+1:size(x,2),:);
figure(6);imshow(bbox5)
%%6
bbox6=x(size(x,1)/4:size(x,1)/2,size(x,2)/2+1:size(x,2),:);
figure(7);imshow(bbox6)
%%7
bbox7=x(size(x,1)/2+1:(size(x,1))/3,size(x,2)/2+1:size(x,2),:);
figure(8);imshow(bbox7)
%%8
bbox8=x((size(x,1))/3+1:size(x,1),size(x,2)/2+1:size(x,2),:);
figure(9);imshow(bbox8)

[m,n,k] = size(x);
out = mat2cell(x,m/4*ones(4,1),n/2*[1,1],k);
