| dc.description.abstract | We describe the use of a three-dimensional textured model of the human head under perspective projection to track a person's face. The system is hand-initialized by projecting an image of a face onto the polygonal head model. Tracking is achieved by finding the six translation and rotation parameters to register a rendered image of the textured model with the video image. We find the parameters by mapping the derivative of the error with respect to the parameters to intensity gradients in the image, use a robust estimator to pool the information and do gradient descent. | en |
