Multiple hypergraph ranking for video concept detection
This paper tackles the problem of video concept detection using the multi-modality fusion method. Motivated by multi-view learning algorithms
multi-modality features of videos can be represented by multiple graphs. And the graph-based semi-supervised learning methods can be extended to multiple graphs to predict the semantic labels for unlabeled video data. However
traditional graphs represent only homogeneous pairwise linking relations
and therefore the high-order correlations inherent in videos
such as high-order visual similarities
are ignored. In this paper we represent heterogeneous features by multiple hypergraphs and then the high-order correlated samples can be associated with hyperedges. Furthermore
the multi-hypergraph ranking (MHR) algorithm is proposed by defining Markov random walk on each hypergraph and then forming the mixture Markov chains so as to perform transductive learning in multiple hypergraphs. In experiments on the TRECVID dataset
a triple-hypergraph consisting of visual
textual features and multiple labeled tags is constructed to predict concept labels for unlabeled video shots by the MHR framework. Experimental results show that our approach is effective.
