Region feature based similarity searching of semantic video objects

New video representations based on semantic objects (e.g., MPEG-4) provide great potential for content-based video searching. In this paper we present an efficient query model for similarity searching of video objects based on localized region features and spatial-temporal structures. The query model is barred on an existing framework on region-level video query, but addresses several new issues like right spatio-temporal relationships effective performance of the proposed approach.
