In DMVC, we have more than one options of sources available for construction of side information. The newer techniques make use of both the techniques simultaneously by constructing a bitmask that determines the source of every block or pixel of the side information. A lot of computation is done to determine each bit in the bitmask. In this paper, we have tried to define areas that can only be well predicted by temporal interpolation and not by multiview interpolation or synthesis. We predict that all such areas that are not covered by two cameras cannot be appropriately predicted by multiview synthesis and if we can identify such areas in the first place, we don-t need to go through the script of computations for all the pixels that lie in those areas. Moreover, this paper also defines a technique based on KLT to mark the above mentioned areas before any other processing is done on the side view.<\/p>\r\n","references":"[1] Girod, B.; Aaron, A.M.; Rane, S.; Rebollo-Monedero, D., \"Distributed\r\nVideo Coding,\" Proceedings of the IEEE , vol.93, no.1, pp.71-83, Jan.\r\n2005\r\n[2] Guol, X.; Lu, Y.; Wu, X.; Gao, W.; and Li, S. \"Distributed Multi-View\r\nVideo Coding,\" Proc.
