thanks a lot for your replay
your write, it will be better if I could solve the solution from earlier stages as reordering the bordered get worst so far

I tried your code and started it with
grayImage = imread('n.png');
grayImage=rgb2gray(grayImage);

but I got this result

You didn't adjust the threshold for your image, did you?
You also may have to adjust the window size because it doesn't look
like it's getting the right edge of the man.
Post your original image. I can't do anything (easily) with just a
screenshot.

I don't know how to adjust it :(
this is the original image

I follow your procedure and implemented the following code

% Reorder the Matrix s
[w,q]=size(s);
%n=x-1;
u=1;
for k=1:w

if((s(k,1)~= 0) && (s(k,2)~= 0))
A(u,1)=s(k,1);
A(u,2)=s(k,2);

s(k,:)=0;
[w,q]=size(s);

i=1;

for o=1:w
if((s(o,1)~= 0) && (s(o,2)~= 0))
xt=s(o,2);
yt=s(o,1);

dt(i,1) = sqrt((xt-A(u,2))^2 + (yt-A(u,1))^2);
dt(i,2) = yt;
dt(i,3) = xt;
i=i+1;
end
end
u=u+1;
mind = min(dt(:,1));
idx = find(dt(:,1)== mind);

[t,tt]=size(idx);
if(t>1)
for p=1:t
A(u,1)=dt(idx(t),2);
A(u,2)=dt(idx(t),3);
u=u+1;
idx2 = find(s(:,1)== dt(idx(t),2));
s(idx2,:)=0;
[w,q]=size(s);
end
else
A(u,1)=dt(idx,2);
A(u,2)=dt(idx,3);
u=u+1;
idx2 = find(s(:,1)== dt(idx,2) & s(:,2)== dt(idx,3));
s(idx2,:)=0;
[w,q]=size(s);
end
[w,q]=size(s);
end
end
disp(A);

it is run correctly and draw the border but not in the circle order that I need
I don't what is the wrong
it becomes complicated more and more :(

I posted my image here
hope you can help me

final chance for me
