This paper presents an original approach to video shot retrieval, which is an adaptation of the common text-based paradigm. The idea of our approach is to describe images using a small number of visual elements chosen in a Visual Dictionary. The user may select some elements from the Visual Dictionary to compose a query and search for specific video shots. In our approach, we automatically compute those visual elements to compose a Global Visual Dictionary, and we select the most representative to build a Query Visual Dictionary. We propose a method to evaluate automatically the efficiency of this Query Visual Dictionary for retrieving shots, and we present experimental results on the TrecVideo BBC Rushes task.
