Most of the 3D displays today rely on stereopsis to create 3D perception. In this paper, we propose to improve user\u2019s depth perception by tracking their motions and creating motion parallax for the rendered image, which can be done even with legacy displays. Two enabling technologies, face tracking and foreground\/background segmentation, are discussed in detail. In particular, we propose an efficient and robust feature based face tracking algorithm that is capable of estimating the face\u2019s location and scale accurately. We also propose a novel foreground\/background segmentation and matting algorithm with time-of-flight camera, which is robust to moving background, lighting variations, moving camera, etc. We demonstrate the application of the above technologies in teleconferencing on legacy displays to create pseudo-3D effects.<\/p>\n<\/div>\n<p><!-- .asset-content --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Depth perception, or 3D perception, can add a lot to the feeling of immersiveness in many applications such as 3D TV, 3D teleconferencing, etc. Stereopsis and motion parallax are two of the most important cues for depth perception.
