Abstract
The method and apparatus for generating a reference video sequence of images 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 value between frames in the video sequence, establishing a threshold value for transitions and dropping those frames whose transitions from frame to frame are below the threshold value. The reference video analysis may be performed on a single user system or over a network system including a number of workstations.
