Can anyone suggest better ways....

I have an application what is looking at a 64x64 pixel image of space objects
(starts, satellites, junk...etc)...  I need to be able to associate pixels
that are above a given threshold into a probable object so that I can point
a telescope at them.  Currently, the method is to just take pixels that have
no "off" pixels between them and call them an object.  Several alternatives
are:

Scanning the image with a quad-cell centroid seeing when thing come above
a given power and error level.

Looking at local maxima...

Any other reasonable alternatives that can be done with a small amount of
compute?
