[racket] digital image processing

hello
yesterday one of my friend show me his image processing program.

I was so suprised that I am finding about digital image processing.
(since I heard that lisp and its dialect is good for artificial
intelligence)

I think first thing I have to do is transfer the image from camera to
computer in real time.
I connected the camera and computer with cable
the cable is consist of usb, yellow, white connector and another side, usb
connector.
so.. for now,
could you tell me what do I have to do next?

thanks in advanced
