[vox-tech] count pixels

Hello,  I need to process some images and count the number of pixes of a
given color.

A little background.  I want to take pix of leaves against a mat
background.  The leaves are then subjected to damage.  I'll then take a
duplicate photo.  Now what I want to do is subtract out the colors of the
leaf leaving only a two tone image.

I was hoping to find a way to then use ImageMagick or Gimp to count the
pixels of color so I can then get a percent change between the two images.

Does anybody know how to get ether of these two programs to give this type
of information.  Actually any software would be help full.
