The visual information of a surveillance system should provide extended and just-in-time perception in monitored environments. However, delivering visual information of surveillance from nonstationary providers, such as mobile cameras, to designated end-users over bandwidth-limited networks is a challenging task. In this paper, for transmitting visual objects of interest, an embedded spatial coding...
Data communication between mobile security robots over the network is an important component in a surveillance system. Because of limited bandwidth, transmission delay, and package loss, real-time video transmission may pose some challenges. In this paper, three steps of image data reduction before transmission are proposed and discussed in detail. The first one is temporal sampling, which selects...
