Using RGB color of pixel to control serial output

Hi, I'm quite new to this whole Max/msp/Jitter Scene. I've made alot of noise with max though and find it really fun and nice to play around with. Now I'm currently trying to do my graduation assignment and I want to know if anyone could help me getting started in this jitter scene. I've found some tutorials and papers about max/msp and jitter but I could always use some more. :D

And about my title of the post this is actually what I'm trying to accomplish, that is to use a live video feed, and jusing the center pixel as a color sensor wich could then be used to control the amount of color from each LED.

This is a similar thing to what I wan't to accomplish, I just want to try and use a interactive color changer so it could match the outfit you're wearing.
