Abstract
In a system and method for generating a synopsis video from a source video, at least three different source objects are selected according to one or more defined constraints, each source object being a connected subset of image points from at least three different frames of the source video. One or more synopsis objects are sampled from each selected source object by temporal sampling using image points derived from specified time periods. For each synopsis object a respective time for starting its display in the synopsis video is determined, and for each synopsis object and each frame a respective color transformation for displaying the synopsis object may be determined. The synopsis video is displayed by displaying selected synopsis objects at their respective time and color transformation, such that in the synopsis video at least three points that each derive from different respective times in the source video are displayed simultaneously.
