Method for representing contents of a single video shot using frames

摘要

A computer implemented method provides a representative frame (Rframe) for a group of frames in a video sequence. The method comprises selecting a reference frame from the group of frames and storing the reference frame in a computer memory. The method defines a peripheral motion tracking region along an edge of the reference frame and successively tracks movement of boundary pixels in the tracking region, symbolizing any of the length of the shot and the presence of any caption.
