I do not have the horsepower to manage too many standalone projects. Keeping a piece of code working and clean is something I can do, but I do not want to deal with the overhead of another git repository, luarocks settings, etc.
OpenCV is also not a very easy project to compile and install, so my plan is to provide binary installations for rubyk which contains opencv bindings (and all required libs).
If you are just interested in the bindings, the simplest solution is probably to:
> cd lubyk
> mkdir build
> cd build
> cmake ..
> make cv
lib/cv/vendor.so (opencv lib as so object)
I just moved the files into the latest head and tested compilation on Mac OS X. The version of openCV I am linking against is not the latest but it works (I have not rewritten the testing code, but it loads and I can create a cv.Mat).
As I said, this is a "raw" binding without any helpers to access raw matrix data and such. If anyone wants to enable pixel access with:
m = cv.Mat(300, 300, cv.CV_8UC1)
for i=1,300 do
for j=1,300 do
m[i][j] = i * j * 255 / 90000
I'd be *very* glad to include such helpers... (m[i] could return m->row() if rows > 1 or the pixel value if rows == 1).

I'm interested in OpenCV bindings for Lua, I've been trying to create
complete bindings myself, using the same generator we use in Lqt,
however without much luck (the OpenCV library headers are not as well
organized as Qt).
Are you planning to release it as standalone library?
