摘要: In this paper, we present an automatic and efficient approach to the capture of dense facial motion parameters, which extends our previous work of 3D reconstruction from mirror-reflected multiview video. To narrow search space and rapidly generate 3D candidate position lists, we apply mirrored-epipolar bands. For automatic tracking, we utilize spatial proximity of facial surfaces and temporal coherence to find the best trajectories and rectify statuses of missing and false tracking. More than 300 markers on a subject's face are tracked from video at a process speed of 9.2 frames per second (fps) on a regular PC. The estimated 3D facial motion trajectories have been applied to our facial animation system and can be used for facial motion analysis.
