AbstractA computer-implemented method for generating a video database index for indexing a video database comprising a plurality of video frames, the video database index comprising a plurality of index frames, wherein each video frame within the video database has a unique location within the video database. According to a preferred embodiment of the invention, the video frames of the video database are transmitted to a processor. A processor generates the index frames of the video database index in accordance with the amount of change occurring in images depicted by the video frames of the video database. Each of the index frames represents a unique video sequence of a plurality of video sequences that constitute the video database. Each video sequence comprises a sequence of video frames of the video database. Also, each video sequence has a unique location within the video database.
