英文摘要 | A scheme on shot content analysis for two video retrieval applications, shot retrieval and scene structure extraction, is presented. To characterize the temporal content variations in one shot, two descriptors: Dominant Cola Histograms and Spatial Structure Histograms, are developed. By fusing temporal information into color content, Dominant Color Histograms for a group of frames are trying to capture the dominant colors with longer duration, which would be the colors of the focused objects or background. Spatial Structure Histograms is a set of features extracted from color-blob maps to describe spatial information for an individual frame. A shot with significant content changes can be segmented into several subshots that are of coherent content, and shot similarity measure can be computed from the similarity between corresponding sub-shots. Scene structure is extracted by analyzing the competition of splitting and merging forces. Experimental results on real-world sports video show that the proposed approaches can achieve the best performance on shot retrievals and have promising results on scene structure extraction.; EI; 0; 8; 1577-1585; 13 |
