I = imread('P1_G4_9.png') ;
[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)

use imresize and increase the dimensions of your image.

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().
