On the effective clustering of multidimensional data sequences

Abstract

In this paper, we investigate the problem of clustering multidimensional data sequences such as video streams. Each sequence is represented by a small number of hyper-rectangular clusters for subsequent indexing and similarity search processing. We present a linear clustering algorithm that guarantees the predefined level of clustering quality, and show its effectiveness via experiments on various video data sets.
