Plus IIRC new features are no longer always available via the C API. I'm going to second this. I need to program computer vision a lot, but I'd like to do it in something a bit better than C++.

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.

Could you post those?

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.

Too many acronyms floating around in my head.

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