A Content-Based Robust Mode Decision Scheme for Internet Videophone Applications

In this paper, a content-based error resilient RDO mode decision scheme is proposed for Internet videophone applications. The experimental results based on typical head-and-shoulder video sequences under common Internet channel condition show that, comparing with conventional error resilient RDO mode decision schemes, the proposed mode decision scheme improves the average luminance PSNR of visually important foreground area consistently regardless of the packet loss rate.
