I = imread('P1_G4_9.png') ;
imshow(I)
[nx,ny] = size(I) ;
[X,Y] = meshgrid(1:ny,1:nx) ;
C = [mean(X(:)) mean(Y(:))] ;
R = 1:10:100 ;
th = linspace(0,2*pi) ;
x = cos(th) ; y = sin(th) ;
hold on
for i = 1:length(R)
plot(C(1)+R(i)*x,C(2)+R(i)*sin(th),'r')
end

Assuming you have the circles and just need to visualize them, use viscircles().

If you want all the circles you have to, for some reason, extend beyond the image, you're going to have to enlarge the image with padarray(), NOT imresize().
