Face Tracking, Motion Tracking, OpenCV - Free Computer Vision Library
Was looking into how to do face tracking and possibly motion tracking. With face tracking I was hoping I could find a way to track facial expressions, ie the eyebrow position, mouth position, as is done with many CG characters nowadays. OpenCV is an open library by Intel that allows you to carry out various computer vision tasks. Facial tracking is one of the demos that comes with OpenCV.
How OpenCV's facial tracking works can be described in great detail
