Rapidly growing multimedia databases have made efficient content-based search an indispensable operation to fast retrieve similar multimedia objects of users' interests. Typically, multimedia objects are represented by high-dimensional feature vectors in the databases. High-dimensional indexing is a primary approach to achieve quick retrieval. In this paper, we present an optimal one-dimensional indexing...
Given a data point set D, a query point set Q and an integer k, the group nearest group (GNG) query finds a subset of points from D, omega (|omega| les k), such that the total distance from all points in Q to the nearest point in omega is no greater than any other subset of points in D, omega(|omega| les k). GNG query can be found in many real applications. In this paper, exhaustive hierarchical combination...
