This paper addresses the discovery of activities and learns the underlying processes that govern their occurrences over time in complex surveillance scenes. To this end, we propos...
We present a two dimensional temporal structure that has an ever changing present. Relative to each present, there is a past and future. The main representational advantage our tw...
Moving objects (e.g., vehicles in road networks) continuously generate large amounts of spatio-temporal information in the form of data streams. Efficient management of such strea...
This paper attempts to improve our understanding of timed languages and their relation to timed automata. We start by giving a constructive proof of the folk theorem stating that t...
