Abstract

Eye-contact plays an important role for human communications in the sense that it can convey unspoken information. However, it is highly difficult to realize eye-contact in teleconferencing systems because of camera configurations. Conventional methods to overcome this difficulty mainly resorted to space-consuming optical devices such as half mirrors. In this paper, we propose an alternative algorithmic approach to achieve eye-contact by techniques of arbitrary view generation and projective transformations. Experimental results show that the synthesized arbitrary viewpoint images enable the eye-contact favorably.
