Is there any way to avoid overlapping of randomly placed gaussian spots on an image?

I am writing a super resolution simulation to analyze microscopy images. I am adding a large number of randomly placed gaussian spots that are 5x5 pixels large onto a 512x512 pixel image.Is there any way to avoid overlapping of the randomly placed gaussian spots on an image? I am randomly generating the cooridinates for the center pixel of the spot using

r1 = randi(ArraySizeX-6,1,1)+3; r2 = randi(ArraySizeY-6,1,1)+3;

Any help would be appreciated.

Thanks!

Yes. Just keep a binary image of where you're plopping down the 5x5 image template. When it comes time to lay down the next one, just examine the pixels where it would go and see if any of them are true.
