Video tracker

[fxrazno1]

[/size]Hi
I will like to use the VisionLab VCL components to
develop a real time video tracker.
I need to user to click on the video image and then use visionlab
to find a target to lock on.
Then I need to move a pan and tilt video camera according to
the target movement.
You can look to an example here:
http://www.trackertechnology.com/demos.html

Is there a way of doing so, and if so what components of visionlab
should I use and in what way.
If you can send me an example I will appreciate it.
I looked at the TargetsTrackDemo.exe example but I need to keep tracking the object near the mouse click all the time. In the example
the acquired targets change all the time.
Thanks Allot
