a good toolkit:

and another

i've used bot a lot, shelling out to ruby mostly, unfortunately
require hacking in c--. insight has ruby bindings though (via swig).

i think you are going to want to do some filtering in the frequency
domain focusing on edge images (shapes) and colours, possibly warping
to achieve a best fit. whatever you do is going to be entirely custom
- as everything in computer visions tends to be, despite having a
plethora of off the shelf tools to start from.

kind regards.

ps.

i nearly always end up stuff pixels into narrays and doing some manip
there - if nothing else to refine algorithms in ruby before
laboriously re-coding in c-- or c. for this is useful to have
representatvie images that are small and as close to raw as possible.
