Abstract

In general, video is too much lengthy for browsing the contents. So, there are many efforts being made for browsing the content of the video fast and effectively. Video summary is the one of techniques related to those efforts. Video summary comprises a number of key-frames. Therefore, we propose a method to extract key-frames from the video in MPEG compressed domain. Proposed method extracts the simple 2D content curve reflecting the variation of the video content from the MPEG video in the compressed domain, approximates the curve to polygonal lines and then extracts key-frames from the approximated lines effectively and rapidly. Also, proposed method let the user set the number of key-frames.
