METHOD AND SYSTEM FOR PRODUCING A VIDEO SYNOPSIS
First Claim
1. A method for creating a synopsis video by transforming a source sequence of video frames of a first dynamic scene captured at regular time intervals to a shorter synopsis sequence of video frames depicting a second dynamic scene, the method comprising:
- (a) source sequence that show movement of at least one object, each source object being a connected subset of image points from at least three different frames of the source video;
(b) selecting from said subset portions that show non-spatially overlapping appearances of the at least one object in the source sequence; and
(c) copying said portions from at least three different source frames to at least two successive frames of the synopsis sequence without changing the image location of said portions and such that at least one of the frames of the synopsis sequence contains at least two portions that appear at different frames in the source sequence.

Abstract
A computer-implemented method and system transforms a first sequence of video frames of a first dynamic scene to a second sequence of at least two video frames depicting a second dynamic scene. A subset of video frames in the first sequence is obtained that show movement of at least one object having a plurality of pixels located at respective x, y coordinates and portions from the subset are selected that show non-spatially overlapping appearances of the at least one object in the first dynamic scene. The portions are copied from at least three different input frames to at least two successive frames of the second sequence without changing the respective x, y coordinates of the pixels in the object and such that at least one of the frames of the second sequence contains at least two portions that appear at different frames in the first sequence.

21. A data carrier tangibly embodying a sequence of synopsis video frames depicting a dynamic scene, at least two successive frames of said synopsis video frames comprising a plurality of pixels being derived from portions of a source object being a connected subset of image points from at least three different frames of the source video without changing the respective image location of said object and such that at least one of the synopsis video frames contains at least two portions that appear at different source frames.

22. A system for transforming a source sequence of video frames of a first dynamic scene to a synopsis sequence of at least two video frames depicting a second dynamic scene, the system comprising:
-
a first memory for storing a subset of video frames in said source sequence that show movement of at least one object being a connected subset of image points from at least three different frames of the source video, a selection unit coupled to the first memory for selecting from said subset portions that show non-spatially overlapping appearances of the at least one object in the source video, a frame generator for copying said portions from at least three different input frames to at least two successive frames of the synopsis sequence without changing the image location of said object and such that at least one of the frames of the second sequence contains at least two portions that appear at different frames in the first sequence, a second memory for storing frames of the synopsis sequence, and means for coupling a display device to the second memory for displaying the second dynamic scene. - View Dependent Claims (25)
