Systems and methods to automatically edit a video to generate a video
summary are described. In one aspect, sub-shots are extracted from the
video. Importance measures are calculated for at least a portion of the
extracted sub-shots. Respective relative distributions for sub-shots
having relatively higher importance measures as compared to importance
measures of other sub-shots are determined. Based on the determined
relative distributions, sub-shots that do not exhibit a uniform
distribution with respect to other sub-shots in the particular ones are
dropped. The remaining sub-shots are connected with respective
transitions to generate the video summary.
