If you can reduce your images into a list of discrete

there are plenty of routines devised by astronomers
to match up the lists and compute the geometric

No point sources in my case, I am looking mainly for ill-defined areas
at different temperature. Still, may be I can generate "points of
interest" based on local peaks, etc. and apply some of these
techniques. Thanks!
