I know this has been asked a few times before, but that was a few years ago. Are there any reasonably complete and up to date OpenCV bindings for D?

If not, are there any reasonably easy ways to generate them? I tried SWIG and it choked on some of the macros they used, though that may have been because I had no idea what I was doing.

Dammit, when I saw the title I thought someone was announcing they'd made one. I don't know of anyone.

I am a bit foggy on the diffence between openCL and openCV, but is this helpful:

OpenCL is more or less completely unrelated. OpenCV is about computer vision and OpenCL is a cross-platform framework for using devices other than CPUs (e.g. GPUs) for general purpose computing.

Sorry.  Too many acronyms floating around in my head.

Should be easy to write wrapper around the OpenCV C API...

I've done it using swig, and using C++ api (not C api), as well as for
other libs (sfml etc). it requires a bit of tweaking the '.i' file but is
doable. Much better than hand maintaining c wrappers.

Could you post those?

If you don't need all of OpenCV, writing a binding using
DerelictUtil is not that hard.

The main gotchas are:
- you really need an editor with a good column-mode
- taking care not to implement named enums
- taking care to replace long by c_long (resp. with unsigned long)

But of course with the sheer size of OpenCV anything automatic
would be better.

Link? Or at least a how-to? This would be a really valuable asset, the C++ api is a LOT nicer to work with than the C one. Plus IIRC new features are no longer always available via the C API.
