I'm doing also some video analysis to produce music. I have a web cam that i use to generat music with VST plug-ins. My aproach so far has been very "naive". I set an 255 position array with the grey values of the video, and then i choose, say position 100 of the 255 array, set a metro to read that value with an interval of 400ms, and then convert those values to notes. But i wan't something better.
What tools do you recommend? I've heard about GridFlow (although i don't really know what it does) but i use PD and GEM in Windows, so i think GridFlow is out of question (it runs on Linux only, right?). What are the things/tools that you recommend to improve the analysis of the live video to produce music?

It provides you with enough math operators to cook up your own analysis patches/abstractions.

GridFlow on Windows requires Cygwin/GCC, and then, the camera input uses Video4Linux, and the video output requires X11. The latter may be fixed, as you can install X11 on Windows, or you can decide to not do the output, but for the camera you are out of luck. The most you can do is analyse pictures/movies from files.
May I remind people that I need someone to take care of the Windows port and that I'm offering support to volunteers.
