Guidance on controlling motors and image processing

HI,

I am building a new robot in which I'm using image processing. I have connected  a camera to laptop and doing image processing through Matlab.

Now, I want to controll motors through my laptop. How I can do this? Mean how I can connect motors to my laptop?
And next thing is that how I can interlink matlab and motor's controll code, so that motors run following the image processing.
Thanks!
