Modeling and Querying Moving Objects
In this paper we propose a data model for representing moving objects in database systems. It is called the Moving Objects Spatio-Temporal (MOST) data model. We also propose Futur...

Querying Complex Spatio-Temporal Sequences in Human Motion Databases
Content-based retrieval of spatio-temporal patterns from human motion databases is inherently nontrivial since finding effective distance measures for such data is difficult. These...

Convoy Queries in Spatio-Temporal Databases
We introduce a convoy query that retrieves all convoys from historical trajectories, each of which consists of a set of objects that travelled closely during a certain time period....

Spatio-Temporal Modeling of Video Data for On-Line Object-Oriented Query Processing
This paper presents a framework for data modeling ntic abstraction of image/video data. The framework is based on spatio-temporalinformation associated with salient objects in an ...

Spatio-Temporal Aggregation Using Sketches
Several spatio-temporal applications require the retrieval of summarized information about moving objects that lie in a query region during a query interval (e.g., the number of m...
