Peng Fei Xu, David M. J. Tax, Alan Hanjalić · MediaEval · 2011
In this paper, we investigate the possibility of using visual information to improve the text based ranking. Both a structure based representation (using the similarity matrix of the frames of one video) as well as a key-frame based representation (using visual words) is evaluated. It appears that only in some queries the visual information can improve the performance by reranking. The presented experiments on reranking show the limitations and also the potential, for these structural and visual representations
