Abstract
In recent years, eye contact problem always exists in daily video conferencing. Users will feel more comfortable and pay more attention to the conversation with proper eye contact. This thesis proposes a novel virtual view synthesis system. Given two video streams from two cameras located in either side of the monitor (ex: Left and right), the system synthesizes a high quality view-corrected virtual image. In the previous work, synthesized images take lots of time for CPU computation. Special hardware-support may be the only solution if the application needs to be high quality and real-time. However, the performance of our proposed fast scanline based matching algorithm can reach real-time, comparing to certain conventional matching algorithms. To achieve natural virtual image synthesizing, the modified dynamic programming approach is adopted. Artifacts and occlusion problems are also handled. A number of examples demonstrate the high quality results of the proposed algorithm.
