Webcam + Ardunio follow

Hello everyone
I have a project and I need to know if it is possible ta program a kinect whitch is going to start a motor to follow someone


I do not know what a kinect is.
It is fairly straight forward to use arduinos to control motors and create simple navigation for vehicles.
Arduinos do not have enough memory or processing power to handle video form a web cam.

Google "arduino follow me" to find many instances of how other people have tackled similar projects, and also how hard navigation like this can be.
