Typically the neighbors of points under a Delaunay triangulation are  
what can be considered as the 'closest neighbors'. There is a plugin  
to generate the Delaunay triangulation from selected points (http://
wbgn013.biozentrum.uni-wuerzburg.de/ImageJ/delaunay.html). Possibly  
the author knows how to extract the neighbors for each point  
including the distance! from the plugin. In fact it would be a nice  
extension to graph operations in ImageJ.
