Kwon, YM Ferrari, E Bertino, E 2024-01-21T15:15:24Z 2024-01-21T15:15:24Z 2021-09-04 1999-07 0169-023X https://pubs.kist.re.kr/handle/201004/142104 The presentation of multimedia data is not only characterized by precise temporal constraints; also spatial constraints must be taken into account. An important requirement in multimedia systems is thus the integrated modeling of spatio-temporal constraints. Moreover, it is important to devise methods for checking the consistency of the specified constraints. In this paper, we first propose a spatio-temporal object graph (STOG) model that provides an integrated and graphical representation of spatio-temporal constraints. Second, we investigate consistency conditions between spatial and temporal constraints expressed in the STOG model. Then, we present a prototype system implementing the proposed model.
