Kees,

it doesn't really matter, since the dot will be only a reference. The easiest things would work. :)

Hi Davide,

Second question: should the whole dot fall within the ROI or only the center of the dots. In the last case part of the dot will fall outside of the ROI.

Hi Kees,

the ROI will be rectangular shape.

I have a picture of a plate with fouling organisms on it, and I need to
generate 50 dots in the bottom part of the plate and 50 in the top part (two
rectangular ROIs).

A way to go would be to crop the image and generate random dots across the
cropped part, but i have about 800 plates and each picture would be cropped
twice. The time needed would be enormous.

Thank you
Davide
