An alternative to a strict "nearest neighbor" is to generate the pair-wise
distances from each centroid to every other centroid in the image. Compile
these into a "pair-wise difference histogram" of distances.  This is the
equivalent of a 1D autocorrelation function. You will see a peak at the mean
nearest neighbor distance.

Subject: distance between adjacent particles

 
Dear all,
I have an image with many particles, distributed randomly. I'm trying to get
the average distance between a particle with all its closest neighbors but
not all of the particles on the image.
Is there an easy way to do or an existing plugin that allows such
measurement?
 
Many thanks,
