---------------------------------------------
subash:
MATLAB has a nice tutorial on this (except for the "remove any
intensities from the slides itself" part) to demonstrate their image
processing toolbox.  They find the intensities in each spot of an
array of spots on a well plate.  Look around their website or the help
file for it, or ask someone who has the image processing toolbox for
it.
