Video Presentation Board : A Semantic Visualization of Video Sequence

This paper presents a video summarization method to visualizing video sequences in a static image for the purposes of efficient representation and quick overview. It can assist viewers to understand important video contents by revealing essential information of video story units and their relations. We have designed a new method called Video Presentation Board to extract, organize, and synthesize important video information in a succinct and meaningful visual format, which also preserves the elegance of original videos. Specifically, we propose a new video shot clustering method using both visual and audio data for analyzing video contents and collecting important shot information. To represent these important video information properly, we design a multi-level video summarization method to represent the contents and relations of video shots through abstracting both locations and interested objects and characters. Suitable amount of selected video information, with the assistants of special visual languages, is then organized and synthesized according to the relations between video events and temporal structure of the video sequence. We have designed and performed a preliminary user study to evaluate our approach and collected very encouraging results. We believe that this approach seamlessly integrates video analysis and visualization methods to provide visually appealing results. Our approach can be used to assist viewers grasp video contents efficiently, and are especially suitable for documentations and reports.
