Method and system for head tracking and pose estimation
First Claim
1. A method for determining motion of a head, the method comprising:
- generating a sequence of images from a camera looking at a user;
estimating a position and a size of a head of the user in each of the images using a scale-invariant head tracking technique designed to scan the each of the images at all scales; and
determining pose of the head from the position and size of the head.

Abstract
Techniques for performing accurate and automatic head pose estimation are disclosed. According to one aspect of the techniques, head pose estimation is integrated with a scale-invariant head tracking method along with facial features detected from a located head in images. Thus the head pose estimation works efficiently even when there are large translational movements resulting from the head motion. Various computation techniques are used to optimize the process of estimation so that the head pose estimation can be applied to control one or more objects in a virtual environment and virtual character gaze control.
