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 undesirable motion in a video, comprising:

receiving a plurality of video frames, the plurality of video frames being captured by a capture device;

determining a movement of the capture device between one of the video frames and a next one of the video frames;

accumulating the determined movement to determine a maximum movement of the capture device with respect to a reference video frame of the video frames; and

trimming at least a portion of the one of the video frames according to the maximum movement of the capture device such that the movement of the capture device is reduced.

2. The method of claim 1, further comprising enlarging the trimmed video frame.

3. The method of claim 1, further comprising determining at least one reference object in the one of the video frames.

4. The method of claim 3, wherein a movement of the capture device between one of the video frames and the next one of the video frames is determined by analyzing the reference object.

5. The method of claim 1, further comprising:

selecting the reference video frame from the video frames.
