Web-Based User Interface For Query Specification In A Video.. - Saykol (2001) (6 citations) (Correct)
....are selected. The topological relations among the objects are automatically added but the user has to specify the directional relations manually. A simple query is formulated in this fashion and the user can construct compound queries via logical operators in the query interface. Query by Trace [13], is a visual interface for the specification of temporal predicates for temporally changing spatial situations. Two types of primitives are defined, moving point and evolving region, denoting the motion and change in size for salient objects. Queries between two moving points or two evolving ....
....two evolving regions are possible as well as queries between a moving point and an evolving region. Having selected the appropriate primitives for the query, the mouse is traced on the canvas and the spatio temporal predicate sequence is specified according to the mouse locations. As mentioned in [13], this visual specification can be directly used as a visual query interface, or can be integrated into a textual query language for multimedia databases. SVIQUEL [24] is a spatial visual query language with an easy to use query specification interface. An object is represented with its minimum ....

....starting with a small set of elementary ones. We have demonstrated how these concepts can be realized in a relational model and how SQL can be appropriately extended to a spatio temporal query language called STQL to enable the querying of developments. The second application described in [21, 22] deals with the user s problem of comfortably specifying temporally changing topological situations and predicates. For this purpose, we have proposed a visual language which extends existing concepts for visual spatial query languages, that are only capable of querying static topological ....
....new predicates according to his needs. To support the user, we have contributed to a solution of these problems (see also Section 2. 2) by proposing an extension of the well known query language SQL to a spatio temporal query language called STQL [19] and by providing a visual query language [21, 22]. STQL enables us to textually formulate spatio temporal queries that relate to developments of spatial objects over time and that are hence based on spatio temporal predicates. Moreover, a macro definition mechanism allows the user to compose more complex spatio temporal predicates from more ....
