I had the following question. Any help will be really appreciated
 
I have a stack of binary-8bit images with a random distribution of particles; also each image has a different number of particles. I was trying to find out how random the distribution was i.e. how uniformly the particles are distributed across each image.
 
One of the previous mails to this list suggested averaging the shortest distance between all the particles - but that does not show any significant difference between images.
 
Is there a another way to do this?
 
thanks,
Kiran.
