Center node: "sparse camera network for visual surveillance a comprehensive survey"
  Abstract: Technological advances in sensor manufacture, communication, and computing are stimulating the development of new applications that are transforming traditional vision systems into pervasive intelligent camera networks. The analysis of visual cues in multi-camera networks enables a wide range of applications, from smart home and ofﬁce automation to large area surveillance and trafﬁc surveillance. While dense camera networks - in which most cameras have large overlapping ﬁelds of view - are well#R##N#studied, we are mainly concerned with sparse camera networks. A sparse camera network undertakes large area surveillance using as few cameras as possible, and most cameras have non-overlapping ﬁelds of view with one another. The task is challenging due to the lack of knowledge about the topological structure of the network, variations in the appearance and motion of speciﬁc tracking targets in different views, and the difﬁculties of understanding composite events in the network. In this review paper, we present a comprehensive survey of recent research results to address the problems of intra-camera tracking, topological structure learning, target appearance modeling, and global activity understanding in sparse camera networks. A number of current open research issues are discussed.
