A hard-coded graphics handle is a bad start:
getpts(1)
Why are you not passing the handle of the figure/axes?

To expand on Stephen's response: change your code to
function [loc] = get_image_point (I)
fig = figure('name','Doubleclick to set location');
imshow(I);
title('Double click on the center of the ring')
[c r] = getpts(fig);
loc = int32([c r]);
if size(loc)>1
loc = [loc(1,1) loc(1,2)];
end
close(fig);
end
