Refer to the script below:
f = figure;im = image(rand(200, 100, 3));roi = imrect(gca, [5, 10, 40, 30]);title('ROI visible');pause;hold('on');image(rand(200, 100, 3));title('ROI not visible, how to make it visible again?');
At this point, roi still exists but is no longer visible. You can still run get(roi), for instance. How to make it visible again?
Thanks!
