METRIC is currently involved in a collaborative research project with the Army Research Laboratory and Morgan State University. The focus of the research effort is spatial and temporal querying of video databases. The specific objective of this project is to extend existing object-based models, such as the AVIS model, which introduced indexing of video data by focusing on the objects of interest and events in the video. The METRIC research effort will support the development of a model which allows one to perform spatio-temporal queries on the video, including querying spatial relationships between objects in the video and querying moving objects in the video. This research has specific military applications, particularly for the Army which routinely uses video in aerial combat missions to capture the visual aspects of the mission. Unfortunately, the sheer volume of the video archive possessed by the Army makes it impossible to index more than a fraction of this data utilizing current database technology. In addition, METRIC researchers are developing a real time, in-memory database (REID) to support EPC code and RFID Savant interfaces. The database would support the RFID network, with an EPC compliant relational database management system. This real time system is designed to handle the high volumes of RFID data expected in large deployments, that are inevitable as federal agencies such as DOD, and commercial entities such as Wal-Mart implement the utilization of RFID in their operational environments. The in memory database would support the higher throughput that will be required to handle the volume of data processed by RFID readers.
