Abstract

The huge amount of videos currently available poses a difficult problem in semantic video retrieval. The success of query-by-concept, recently proposed to handle this problem, depends greatly on the accuracy of concept-based video indexing. This paper describes a multi-cue fusion approach toward improving the accuracy of semantic video indexing. This approach is based on a unified framework that explores and integrates both contextual correlation among concepts and temporal dependency among shots. The framework is novel in two ways. First, a recursive algorithm is proposed to learn both inter-concept and inter-shot relationships from ground-truth annotations of tens of thousands of shots for hundreds of concepts. Second, labels for all concepts and all shots are solved simultaneously through optimizing a graphical model. Experiments on the widely used TRECVID 2006 data set show that our framework is effective for semantic concept detection in video, achieving around a 30% performance boost on two popular benchmarks, VIREO-374 and Columbia374, in inferred average precision.
