摘要：The method and apparatus for generating a reference video sequence ofimages includes performing a grid analysis of each of the frames of the video sequence,assigning a color value to that frame, calculating the difference in total color valuebetween frames in the video sequence, establishing a threshold value for transitions anddropping those frames whose transitions from frame to frame are below the thresholdvalue. The reference video analysis may be performed on a single user system or over anetwork system including a number of workstations.
