Since the information in video databases can be measured in thousands of gigabytes of uncompressed data, video analysis methods which ignore the redundancy in video sequences can not be considered practical methods. Thus, we integrate the video analysis methods with video compression in order to exploit the redundancy in video sequences. The method is applicable to a wide range of applications in digital libraries and the film industry, which include searching video databases, synthesis and analysis of digital libraries, human-computer interaction, and film producing. Roughly speaking, a shot break is the change from one camera shot to another. In the research literature, the definitions change depending upon the paper.
Many researchers use the movie maker terminology in which a scene is composed of one or more shots.
Shot break detection is useful for a wide variety of real world applications. Video editors and producers usually work in terms of shots and scenes, not individual frames. This work is useful not only in finding shots and deleting shots within a current movie, but also in locating shots and scenes from previous movies. It also gives more search options to the home user. Suppose you have recorded six hours of video from cable.
