Not sure exactly what you are wanting but have you considered using a setup that works somewhat like smart missiles use, where an infrared spot is pointed at the target and a camera just has to keep track of that spot.
I have thought about this before to get a pro video camera to track a scene by having either a infrared spot project on the target or have a somewhat concealed infrared LED on the target. A low res. camera able to see the infrared or perhaps a matrix of infrared sensors can be used to do the tracking. The infrared can be distinguished from other stray infrared perhaps by making it pulse at a set rate.
