For video summarization and retrieval, one of the important modules is to group temporal-spatial coherent shots into high-level semantic video clips namely scene segmentation. In this paper, we propose a novel scene segmentation and categorization approach using normalized graph cuts(NCuts). Starting from a set of shots, we first calculate shot similarity from shot key frames. Then by modeling scene...
In this paper, we propose a method for two typical mid-level descriptors extraction of soccer video: view type and playfield position. The output reveals high-level structure of the soccer video. After the robust playfield segmentation, we use the grass-area-ratio and the boundary approximate lines between playfield and non-playfield to classify each frame into three kinds of view types according...
