Efficiently support concurrent queries in multiuser CBIR systems - Sasmita Mishra - 08-17-2017
Abstract
Various techniques have been developed for different query types in content-based image retrieval systems such as sampling queries, constrained sampling queries, multiple constrained sampling queries, k-NN queries, constrained k-NN queries, and multiple localized k-NN queries. In this seminar , propose a generalized query model suitable for expressing queries of different types, and investigate efficient processing techniques for this new framework. We exploit sequential access and data sharing by developing new storage and query processing techniques to leverage inter-query concurrency. Our experimental results, based on the Corel data set, indicate that the proposed optimization can significantly reduce average response time in a multi user environment, and achieve better retrieval precision and recall compared to two recent techniques.
