Scene and activity identification in video summary generation based on motion detected in a video
First Claim
1. A method for identifying scenes in captured video for inclusion in a video summary, the method comprising:
- accessing a video, the video including a plurality of frames;
determining a velocity of content of individual frames of the video;
determining an acceleration of the content of the individual frames of the video based on at least two of the velocities of the content of the individual frames;
determining a score for the individual frames of the video based on the velocity and the acceleration of the content of the individual frames;
selecting one or more of the individual frames of the video based on the determined scores;
identifying, for individual selected frames, a corresponding video scene, the corresponding video scene comprising a first amount of the video occurring before the selected frame and a second amount of the video occurring after the selected frame; and
selecting one or more of the identified video scenes for inclusion in the video summary.

Abstract
Video and corresponding metadata is accessed. Events of interest within the video are identified based on the corresponding metadata, and best scenes are identified based on the identified events of interest. In one example, best scenes are identified based on the motion values associated with frames or portions of a frame of a video. Motion values are determined for each frame and portions of the video including frames with the most motion are identified as best scenes. Best scenes may also be identified based on the motion profile of a video. The motion profile of a video is a measure of global or local motion within frames throughout the video. For example, best scenes are identified from portion of the video including steady global motion. A video summary can be generated including one or more of the identified best scenes.
