Video stream retrieval based on temporal feature of frame difference

In recent years, we can easily access an enormous amount of digital video stream in standardized video format such as MPEG and etc. However, it is not so easy to find a desired video stream from video database in reasonable short time. Some efficient searching methods in terms of computational cost are definitely required for video stream retrieval. In this paper, we propose a novel method for video stream retrieval using a video stream as search-key. The objective is to find a part of the video stream stored in the database that is similar to the given video stream key. This method extracts some characteristics in frame transition in video streams, and utilizes the characteristic for the similarity matching. Some experimental results are also shown to verify the efficiency of the proposed method.
