Abstract:
1. A computer-implemented method for creating a synopsis video by transforming a source video that includes a sequence of video frames of a first dynamic scene captured by a video camera, to a shorter synopsis video that includes a sequence of video frames depicting a second dynamic scene, the method comprising: (a) obtaining a subset of video frames in said source video that show movement of at least two non-background source objects, each source object being represented by a set of pixels in at least three different frames of the source video; (b) selecting at least two source objects from said source video, and sampling from each selected source object one or more non identical synopsis objects by temporal sampling; (c) determining for each synopsis object a respective display time for starting its display in the synopsis video; and (d) generating the synopsis video, wherein the synopsis video is characterized by a shorter duration than the source video, by displaying the selected synopsis objects each at its respective determined display time while maintaining the spatial location of the synopsis objects as the spatial location of their respective source objects as captured in the source video, wherein for at least two source objects, each derived from different respective times in the source sequence, their respective synopsis objects are displayed simultaneously in the synopsis video, and wherein at least two of the selected synopsis objects are displayed in the synopsis video in a chronological order of appearance that is different from the chronological order of appearance of their corresponding source objects in the source video.
