Yes, sorry I misunderstood the problem.
Well your grid dots and the noise blobs are completely different. You probably
can tell them apart by morphological analysis of size and shape.
Once you have all the right dots in your Results Table, then chose one
randomly from the list and floodfill it black at the XStart YStart point. That
will remove it.

For the "degradation of the dots" it depends what you want to do. I do not
think there is a simple command to do that. You could diffuse random particles
in the background until the stick to one dot, or vectorise the perimeter and
add extra points to it, or add random dots to the image and use binary
reconstruction to retrieve the modified ones based on the ones existing in the
original.
Cheers
