1. 1 Model-Based Head Pose Estimation Axel Weissenfeld

2. 2 WP7: Motion Analysis and Tracking Model-based head motion estimation algorithm is designed Algorithm estimates the head pose due to tracking feature points Large out-of-plane rotations lead to pose errors, if feature points are not updated Research area: Strategies in literature: Never update feature points Always update feature points We propose a new strategy for an automatic update of feature points

3. 3 texture update: our proposed method always update: error due to drift; never update: see videosee video WP7: Motion Analysis and Tracking
