can u pls explain this code in detail?

function [Im_rgb phi] = region_seg_demo(Im_rgb,I)

m = zeros(size(I,1),size(I,2));          %-- create initial mask
m=m/2;
[s1 s2 s3] = size(I);
m(10:s1-10,10:s2-10) = 1;

I = imresize(I,.5);  %-- make image smaller 
Im_rgb = imresize(Im_rgb,.5);
m = imresize(m,.5);  %     for fast computation

[seg phi] = region_seg(I, m, 500); %-- Run segmentation
% figure;
% imshow(Im_rgb); hold on;
% contour(phi, [0 0], 'w','LineWidth',4);
% contour(phi, [0 0], 'k','LineWidth',2);
% hold off; title([num2str(i) ' Iterations']); drawnow;

Wow, the next "explain in detail" question. ASHA, this is not efficient for obvious reasons. Please try to use the forum such, that neither your time nor the time of the readers is wasted.

Last time I explained some code "in detail" it took me more than half an hour to write up the explanation for 10 lines, most of which were empty. If you do not understand MATLAB syntax then study it.
