Multisensor surveillance systems based on image and video data

In this paper, a brief state of the art in the field of advanced surveillance systems is given. The goal is to provide a framework under which to describe the different contributions to research presented in the special session on multisensor surveillance systems based on image and video data. Some problems of interest considered by current research are highlighted starting from the necessity of augmented perceptual capabilities, to the use of video object based coding techniques, going to the capability of extending current video representation techniques in order to make it possible to easily correlate, recognize, index and retrieve multisensor video observations.
