I have seen applications that use a camera to track an object by outlining it or what ever method they have to track it. I was wondering how hard would it be to create software that can use a web cam to track an object like a piece of paper with some type of color marker on it but at the same time have that web cam mounted on a pan tilt system so that it can follow it. I am no means advanced in coding I'm more on the mechanical side but I'm only starting to get into coding so this is more of a project i don't mind waiting to do for a while or a goal to work on. But if there is any advice that anyone might not mind sharing that would be great thanks.

That looks like that would help alot but I'm more of an open source person and try to not spend to much money do you know of any free programs like that. Thanks for sharing that though.
You could try looking at Processing, in particular some of the computer vision libraries here: http://processing.org/reference/libraries/#computer_vision
Also, look into OpenCV (http://opencv.willowgarage.com/wiki/FullOpenCVWiki). Doesn't Processing use this - can't remember?
Note that what you are wanting to do isn't as easy as you think, although the solutions presented to help you toward this task make it easier than rolling your own solution. Many, many books and thesis' have been written over the past 40+ years dealing with machine vision and tracking. While the solutions presented will help you, if you are serious about implementing and understanding what is going on, do some more research, it will only help you.
