I need to take a randomized point grid with the code:
x=rand(1,50)*5
y=rand(1,50)*5
scatter(x,y)
And overlay it onto a picture. I am not sure if this can be done or how to do it? Any help would be appreciated!

I = imread( 'MyImage.png' ) ;
x = rand( 1, 50 ) * size( I, 2 ) ;
y = rand( 1, 50 ) * size( I, 1 ) ;
imshow( I ) ;
hold on ;
scatter( x, y ) ;
