Analyse a video stream for creating music

Hi there,

I just need an easy way to get information (those like contrast, color, hue, gamma etc.) out of a video-stream. I want these Information to cue generators and effectprcessors to create music. Do you have an idea? Sure you have, but I just got started with vvvv.
Thanx for help.
