Multi-sensor Information Fusion by Query Refinement [chapter]

Chang Shi-Kuo, Gennaro Costagliola, Erland Jungert
2002 Lecture Notes in Computer Science  
To support the retrieval and fusion of multimedia information from multiple real-time sources and databases, a novel approach for sensor-based query processing is described.  ...  The approach is also applicable to evolutionary queries that change in time and/or space, depending upon the temporal/spatial coordinates of the query originator.  ...  If the query is to find un-occluded objects and the sensor reports only an occluded object, then the query processor is unable to continue unless we modify the query to find occluded objects.  ...

An Approach to Resolve Data Model Heterogeneities in Multiple Data Sources

C. Chirathamjaree
2006 TENCON 2006 - 2006 IEEE Region 10 Conference  
This paper presents an approach to resolve data model heterogeneities in databases and legacy systems through mediation and wrapping techniques.  ...  To gain a competitive advantage, it is imperative for executives to be able to obtain one unique view of information, normally scattered across disparate data sources, in an accurate and timely manner.  ...  Multiple local schemas are consolidated to create the global schema. Users are able to use one database language to query the global schema without understanding any local schemas.  ...

Automatic query mapping among genomic databases: a pilot exploration

K H Cheung, P Nadkarni, P Miller, D G Shin
1998 Proceedings. AMIA Symposium  
We describe an approach that allows a query issued against one database to be automatically mapped to an equivalent query against another structurally different database.  ...  To do so, the user needs to issue the same query across multiple databases.  ...  This often requires the same query to be applied to multiple databases.  ...

Fig. 3 shows how exclusive versus shared locks impact changes to an object. We do not use this approach in SEED for two reasons.  ...  It is an object/relational da- tabase (a variant of the nested relation approach) because it fully supports relational database constructs.  ... 

Mobile Multi-View Object Image Search [article]

Fatih Calisir, Muhammet Bastan, Ozgur Ulusoy, Ugur Gudukbay
2018 arXiv   pre-print
At query time, it is possible to capture multiple views of an object from different viewing angles and at different scales with the mobile device camera to obtain richer information about the object compared  ...  We performed a comprehensive analysis of early and late fusion approaches using various similarity functions, on an existing single view and a new multi-view object image database.  ...  When the query or database objects have multiple images, we must employ fusion methods to process the queries and find best k matching database objects.  ...

Multiple queries for large scale specific object retrieval

Relja Arandjelovic, Andrew Zisserman
2012 Procedings of the British Machine Vision Conference 2012  
Given a textual query (e.g. "coca cola bottle"), our approach is to first obtain multiple images of the queried object using textual Google image search.  ...  These images are then used to visually query the target database to discover images containing the object of interest.  ...  Using multiple images of the object to query the database naturally alleviates to some extent all of these problems.  ...
