determining a central frame of a frame cluster of the plurality of frame clusters, wherein the central frame is a frame in the frame cluster that is the closest to the center of the frame cluster; and
in response to a similarity of the focal regions between the central frame and another frame in the frame cluster satisfying a threshold, removing the other frame from the segment.
