using macbook built in iSight webcam with Jitter

hi there,
I’m new to the forum. So, please be gentle!
I am a relative novice with max / msp- painstakingly used it for a project a long time ago.
I have an apple macbook, and use it to perform live occasionally. Looking through the artist videos / interviews on the C74 homepage, I saw a college tutor mentioning a pupil who made a jitter / max patch that read her movements and reacted with sounds,
i thought this was pretty inspiring, and I was wondering if you think it’ll be possible to do something similar using the macbook’s built in webcam???
If so, I might have to dive in and get hold of Jitter?
thanks!
tom

Hi Tom,

Yep. that’s absolutely possible. The built-in cam works as any webcam
or camera you can attach to you computer. You can bring it’s images
into jitter using jit.qt.grab and go from there. I’ve been recently
pointed to cv.jit (computer vision), a set of externals you can use
it to analyze the incoming footage of the built-in cam. There’s also
a tutorial coming with jitter (also if you use the 30 day trial), nr
25 colortracking that shows how to do some basic colortracking with
jit.findbounds, the help file of this object shows another example
generating tones according to the position of the color that’s been
tracked… Wesley Smith also made some nice externals for tracking,
xray.jit.probsegment and a bunch of other xray.jit externals… and
there’s cyclops from cycling74 which you can try out… for the rest,
this forum will also get you places I guess.

good luck and have fun checking it out and playing around.

correction, it’s not the jit.findbounds help, but the patcher
bballtracking in tutorial 25.
