A Multi-expert Approach for Shot Classification in News Videos

In this paper we propose a multi-expert approach for anchor shot detection in news videos. The proposed Multi-Expert System (MES) combines three algorithms selected among those presented in the literature that are model-free and do not require a specific training phase. In order to assess the performance of the proposed MES, we built up a large database, significantly wider than those ones typically used in the field. Reported experimental results show not only that proposed system performances are better than the ones of original experts but also the smart use made by the MES of strengths and weaknesses of each expert.
