title = "An adaptive H.264 video protection scheme for video conferencing",
abstract = "Real-time video communication such as Internet video conferencing is often afflicted by packet loss over the network. To improve the quality of video, error protection schemes have been introduced based on FMO in H.264 whose encoding efficiency is unacceptable. This paper presents a novel region of interest (ROI) protection scheme that can accurately extract ROI area using facial recognition and greatly speedup video encoding based on feedback using ×264 codec implementation. In this scheme, the video receiver uses a packet loss prediction model to predict whether to send feedback to the video sender that dynamically adjust the ROI protecting scheme. Experiments prove that the quality of the ROI area can be effectively improved by the scheme whose encoding performance increases by 50 times compared with FMO based algorithms.",
