The process of video indexing determines the quality of video retrieval. We present a modularization of indexing systems in which dependencies of components are made explicit. We stress the impact of human interaction in the architectural scheme, as the semantic gap between automatic abstractions and semantic indices requires human intervention. We discuss the components for efficient indexing,...

Given a query fingerprint, the goal of indexing is to identify and retrieve a set of candidate fingerprints from a large database in order to determine a possible match. This significantly improves the response time of fingerprint recognition systems operating in the identification mode. In this work, we extend the indexing framework based on minutiae triplets by utilizing ridge curve parameter...

Subject indexing is an intellectual intensive process that bears many inherent uncertainties. Existing subject index systems generally produce binary outcomes on whether assigning an indexing term or not, which does not sufficiently reflect to which extent the indexing terms are associated with documents. On the other hand, probabilistic models have seen great success in capturing the uncertain...

Complex query types huge data volumes and very high read update ratios make the indexing techniques designed and tuned for traditional database systems unsuitable for data warehouses DW We propose an encoded bitmap indexing for DWs which improves the performance of known bitmap indexing in the case of large cardinality domains A performance analysis and theorems which identify properties of goo...

In wireless data broadcast systems, popular information is repetitively disseminated through possibly multiple communication channels to mobile clients using various types of battery-operated devices. Access latency and tuning time are two conflicting performance metrics used in such systems to measure their efficiency. In practice, different application and usage scenarios may require differen...
