Abstract
A computer-implemented method of positioning a video frame within a collage cell includes, for a given one of a plurality of video frames, generating a polygon encompassing a portion of the respective video frame containing at least one visual element. The polygon has a center position corresponding to a first point within the respective video frame. The center position of the polygon of a given frame is then changed to a new center position based at least in part on an average center position of polygons encompassing portions of at least two consecutive video frames containing the visual element(s). The new center position corresponds to a second point within the given video frame. Next, a cropped portion of the given video frame encompassed by the polygon having the new center position is generated and displayed within a collage cell of a graphical user interface.
