Hi Grace,

I don't know if anyone has tried to use OpenCV within IDL. But, since it has a C interface, it should be "relatively" straightforward to write some C-code wrappers for IDL, and bundle them up into a DLM (dynamically loadable module). I would suggest looking at the CALL_EXTERNAL and MAKE_DLL routines in IDL. If you're really lucky, you might be able to use the AUTO_GLUE keyword to CALL_EXTERNAL, and then you wouldn't even need to write the wrappers. It depends upon how complex the API is for OpenCV.

Reference guide for call_external and make_dll:

IDL External Development Guide (hopefully you won't need this!):

Hope this helps.
Cheers,
