Abstract

Summarization of video content including football.

Claims

1. A method of processing a video including football comprising:

(a) identifying a plurality of segments of said video, wherein the start of said plurality of segments is identified based upon detecting multiple substantially parallel spaced apart substantially straight lines, where each of said segments includes a plurality of frames of said video; and

(b) creating a summarization of said video by including said plurality of segments, where said summarization includes fewer frames than said video.

2. The method of claim 1, wherein at least three of said straight lines intersect at substantially the same location.

3. The method of claim 1, wherein said straight lines are generally white.

4. The method of claim 1, wherein said substantially parallel lines are on a generally green background.

5. The method of claim 1, wherein said substantially parallel lines are on a generally brown background.

6. A method of processing a video including football comprising:

(a) identifying a plurality of segments of said video, wherein the start of said plurality of segments is identified based upon identifying multiple spaced apart generally white lines, where each of said segments includes a plurality of frames of said video; and

(b) creating a summarization of said video by including said plurality of segments, where said summarization includes fewer frames than said video.

7. The method of claim 6, wherein said white lines are substantially parallel to one another.

8. The method of claim 6, wherein at least three of said white lines intersect at substantially the same location.

9. The method of claim 6, wherein said white lines are on a generally green background.

10. The method of claim 6, wherein said white lines have a sufficient length.

11. The method of claim 6, where said length is based upon the size of a generally green region of said video.

12. A method of processing a video including football comprising:

(a) identifying a plurality of segments of said video, wherein the start of said plurality of segments is identified based upon identifying multiple spaced apart lines, wherein said lines contrast with the background, where each of said segments includes a plurality of frames of said video; and

(b) creating a summarization of said video by including said plurality of segments, where said summarization includes fewer frames than said video.

13. The method of claim 12, wherein said lines are generally white.

14. The method of claim 12, wherein said background is generally green.

15. The method of claim 12, wherein said lines are substantially parallel to one another.
