Overview of the IEEE 1857 surveillance groups
Among the multiple application-oriented video groups of IEEE 1857 video part, surveillance groups are the first specific video coding standards targeting on the exploring surveillance system. In this paper, we firstly present an overview of the technical features and characteristics of the Surveillance Baseline and Surveillance Groups. The video coding technologies are then described in greater detail on three main directions, including the background modeling based prediction techniques for high-efficiency surveillance video coding, error resilience methods for channel-noisy surveillance video transmission and the high-level syntax for surveillance video analysis. The surveillance groups can provide a good support for kinds of video analysis applications of computer vision and make the video transmission more applicable for noisy channels. Moreover, experimental results show that the background modeling based prediction techniques can well exploit the special characteristics of surveillance video and double the traditional compression performance.
