Dear all,
Does anyone know of a script or protocol for producing a histogram of the
shortest distances between particle centroids and, say, 100
randomly-generated particles in the intervening space? I am not trying to
do a nearest-neighbor analysis (which only gives the average distance
between each existing particle in an image and its closest neighbor).
Rather, I am trying to generate a profile (histogram) that represents the
average distances between random points in the interstitial space and their
closest particle centroid (e.g., used in studies of Krogh diffusion).
If anyone out there has experience with this method, I'd greatly appreciate
a nudge in the right direction. Every search I attempt on Google brings me
to nearest-distance plugins (which is similar, but not quite the same).
Thanks!
