OpenCV integration and VideoIn object
Gaspard Bucher
1. OpenCV integration
I have completely rewritten most of the build system and included
OpenCV sources directly into rubyk and it all compiles fine with 64bit
support. All OpenCV is there except highgui (which we won't need since
rubyk should provide windows and file IO), and cvaux (advanced and
experimental computer vision stuff depending on highgui).
Since most (if not all) solutions to build OpenCV on Mac OS X fail
(macports, svn snapshot), this might be the only working build of
OpenCV on Snow Leopard... ;-)
2. Video In
Retrieving a video signal was not an easy task. I tried some solutions
from different frameworks, but they all rely on the old 32bit
QuickTime API and their solutions usually imply importing a *ton* of
uninteresting code (with lots of globals...).
So after countless hours deep, deep into pixel buffers, I finally
managed to suck the video signal out of my iSight.
Example: http://bit.ly/b0cUOa
(as always, all this is very "beta" for the moment)

PS: now it's time for OpenCV bindings in Lua...

Congratulations
Can't wait to test it.
Is there some documentation or small example projects for getting
started in rubyk?
Home was long time ago and even then I didn't totally understood how to use it.
By the way, you should meet Théo and David once to see if there is
something doable with their multi-touch screen. It is based on opencv
for blob (touch) detection... so this can be a great toy to adapt
mimas on :-)
