Abstract
A method for summarizing image content from video images received from a moving camera includes detecting foreground objects in the images, determining moving objects of interest from the foreground objects, tracking the moving objects, rating movements of the tracked objects, and generating a list of highly rated segments within the video images based on the ratings.

A method of presenting a summary of a video, the method comprising
- tracking moving objects within the video;
- determining a smoothness value of a trajectory of each tracked object;
- discarding the tracked objects having smoothness values below a minimum threshold smoothness level;
- selecting a period of time within the video that includes at least one of the remaining tracked objects;
- and
- presenting a frame of the video overlaid with all of the remaining tracked objects that are present during the selected period of time.
