Abstract

Included are embodiments for reducing undesirable motion in a video. At least one embodiment of a method includes receiving a plurality of video frames that comprise at least one segment of a video, the plurality of video frames being captured by a capture device and determining a maximum undesired movement of the capture device for the plurality of video frames during the at least one segment. Some embodiments include trimming at least a portion of the video frames according to the determined maximum undesired movement such that the undesirable movement in the video is reduced.

Claims

1. A method for reducing undesired motion in a video, comprising:

receiving a plurality of video frames that comprise at least one segment of a video, the plurality of video frames being captured by a capture device;

determining undesired movement of the capture device for each of the plurality of video frames during the at least one segment; and

trimming at least a portion of the video frames according to a determined maximum undesired movement from among the plurality of video frames such that the undesired movement in the video is reduced.

2. The method of claim 1, further comprising determining a magnitude of undesired movement for at least one of the plurality of video frames.

3. The method of claim 2, wherein determining a magnitude of undesired movement includes determining a vertical motion, a lateral motion, a forward motion, a backward motion, or a rotation.

4. The method of claim 1, further comprising determining at least one reference object in the at least one segment.

5. The method of claim 4, further comprising utilizing the at least one reference object to determine undesired movement for at least one of the video frames.

6. The method of claim 1, further comprising determining whether the video includes desired motion of the capture device.

7. The method of claim 1, wherein the capture device includes a video camera, a still image camera, a computing device, or a communications device.

8. A system for reducing undesired motion in a video, comprising:

at least one computing device; and

a receiving component executable in the at least one computing device, the receiving component configured to receive a plurality of video frames that comprise at least one segment of a video, the plurality of video frames being captured by a capture device;

a first determining component executable in the at least one computing device, the first determining component configured to determine a maximum undesired movement of the capture device for each of the plurality of video frames during the at least one segment; and

a trimming component executable in the at least one computing device, the trimming component configured to trim at least a portion of the video frames according to the determined maximum undesired movement from among the plurality of video frames such that the undesired movement in the video is reduced.

9. The system of claim 8, further comprising a second determining component executable in the at least one computing device, the second determining component configured to determine a magnitude of undesired movement for at least one of the plurality of video frames.

10. The system of claim 9, wherein determining a magnitude of undesired movement includes determining at least a vertical motion, a lateral motion, a forward motion, a backward motion, or a rotation.

11. The system of claim 8, further comprising a third determining component executable in the at least one computing device, the third determining component configured to determine at least one reference object in the at least one segment.

12. The system of claim 11, further comprising a utilizing component executable in the at least one computing device, the third determining component configured to utilize the at least one reference object to determine undesired movement for at least one of the video frames.

13. The system of claim 8, further comprising a fourth determining component executable in the at least one computing device, the fourth determining component configured to determine whether the video includes desired motion of the capture device.

14. The system of claim 8, wherein the capture device includes a video camera, a still image camera, a computing device, or a communications device.

15. A computer readable medium for reducing undesired motion in a video, comprising:

receiving logic configured to receive a plurality of video frames that comprise at least one segment of a video, the plurality of video frames being captured by a capture device;

first determining logic configured to determine a maximum undesired movement of the capture device for each of the plurality of video frames during the at least one segment; and

trimming logic configured to trim at least a portion of the video frames according to the determined maximum undesired movement from among the plurality of video frames such that the undesired movement in the video is reduced.

16. The computer readable medium of claim 15, further comprising second determining logic configured to determine a magnitude of undesired movement for at least one of the plurality of video frames.

17. The computer readable medium of claim 16, wherein determining a magnitude of undesired movement includes determining a vertical motion, a lateral motion, a forward motion, a backward motion, or a rotation.

18. The computer readable medium of claim 15, further comprising third determining logic configured to determine at least one reference object in the at least one segment.

19. The computer readable medium of claim 18, further comprising utilizing logic configured to utilize the at least one reference object to determine undesired movement for at least one of the video frames.
