With standardization of digital video compression such as ISO/IEC MPEG1/2/4 and ITU-T H Series, the use of DVD and digital broadcasts are popularized. Also with widespread use of digital encoder/decoder such as Windows Media, Real Networks,Quick Times, creating digital contents are becoming more easy that digital contents are more common now days. In addition to this, with broadband internet, the base to deliver contents through communication network without any stress is being created. From these circumstances, the efficient mechanism to find desired contents from huge mount of digital multimedia contents such as video and music is being waited for. And there are in fact lots of un-needed data, as well. To solve these tasks, we have developed two systems (Movie Search Engine and Video Editing Support Systems.)

ŚWe have already demonstrated these systems at MPEG-7 Symposium(Waseda University Japan, Sept. 2001). We are planning to demonstrated these at NAB (Las Vegas USA, April 2002) and MPEG-7 3rd Awareness Event(Washington D.C. USA, May 2002).


  • Movie Hunter`Movie Search Engine`

    This is a movie search engine to retrieve demanded video from large video archive.

    Our demo system likens TV broadcasts to video archive and when there is desired video in received video (we have set this to TV commercial as for now), the system will quickly catch this as movie search engine.

    The characteristic of this system is that the amount of process to search is very small. When matching videos, very large device will be needed if all pixels are being used to search and very large amount of process will be needed. For this, we have extracted characteristics from video and compare only these extracted characteristics to reduce the amount of process to search and have succeeded in developing search engine with low process amount.

    Complement: Characteristics used in this system is our proposed characteristics which is equivalent to Color Layout Descriptor from ISO/IEC 15938 Mutlimedia Content Description Interface (MPEG-7)

  • Scene Judge Man`Video Editing Support System`

    This system proposes mechanism to quickly take out desired parts from video sequence and cut the unnecessary parts.

    This system automatically analyses camera work (panning, zooming) of the video and grip information such as the stability of camera work or the hand shake level of each scene for users to see. By using this system, followings are possible.

    Usage‚P.
    When you go on a trip with your handy digital video camera, since video camera is taken by non-professional that the camera work is not stable and includes many handshakes. However, some parts are taken well that you need to know which part of the video is usable. For this, you may use editing soft on market but this will cost you a lot of energy. By using this Scene Judge Man, it is easy to know which part of video sequence includes fewer handshakes very quickly by analyzing camera works of video automatically. Of course, Scene Judge Man provides easy editing tools based on these camera works which makes easy to create digests of your video. (For example, clip together only the scene with stable camera work into 5 min. long)

    Usage‚Q.
    When video editor of TV broadcast station is to make digest video from sports live video, this system may be used. When there is limited time to edit, to automatically know the scene with stable camera work will greatly reduce the amount of work.

    Reminder: This system is to judge the stability of camera work objectively and is not for evaluating the video itself.
