Video Retrieval Method Applied to VOD Systems
A novel type for video-on-demand(VOD)is presented.The user uses the interested part of single image as the query.The system server,which stores the video summary in the whole system,co-segments the frames in video summaries according to the query,and computes the distance between the image and the query.Furthermore,the server can localize and play the video that the user requested.The query can come from the poster or from the frame itself,since it only handles the region of interest(ROI),no constraints are required for the color of the background(out of ROI).Experiments show that it is a novel and effective style for video retrieval,and can be applied in the VOD system.
