Hi,
Unfortunately, AstroImageJ current has no such automated capability
built in. I personally have no experience with galaxy vs. star
recognition, but I would guess that a larger FWHM than the image average
might be indicative of a galaxy. The photometer in AIJ measures FWHM,
but you would need to direct the photometer to the objects of interest
either by hand or with a peak finding algorithm.

I you do develop a plugin that works with base IJ, I would be happy to
help integrate it as an AIJ feature.
