Space-Time Video Montage

Conventional video summarization methods focus predominantly on summarizing videos along the time axis, such as building a movie trailer. The resulting video trailer tends to retain much empty space in the background of the video frames while discarding much informative video content due to size limit. In this paper, we propose a novel spacetime video summarization method which we call space-time video montage. The method simultaneously analyzes both the spatial and temporal information distribution in a video sequence, and extracts the visually informative space-time portions of the input videos. The informative video portions are represented in volumetric layers. The layers are then packed together in a small output video volume such that the total amount of visual information in the video volume is maximized. To achieve the packing process, we develop a new algorithm based upon the first-fit and Graph cut optimization techniques. Since our method is able to cut off spatially and te...
