Hi,
I have selected random points using the below code
m = imread('a.jpg');
figure, imshow(m);
random_num = 50;
l = randi(numel(m), 1, random_num);
m(l) = 255;
figure, imshow(m);
Now I want to draw circle/rectangle for each random points. circle/rectangle for all points will be of equal size.
Can anyone assist me how to do that please.
Added an image for your information.

Try to adjust this protocol to your problem :
L=0.5;
N=100;
for n=1:N
p=randn;
p2=randn;
r=p+L;
r2=p2+L;
x=[p r r p p];
y=[p2 p2 r2 r2 p2]; plot(x,y,'k')
hold on;
end

This is a filter operation. I am 95% sure you cancan get away with using imdilate with a circle or square structral element of your liking. Basically make your randomcpoints 1 and everything else 0, and dilate that image.
