US 7,734,144 B2 · Method and apparatus for editing source video to provide video image stabilization

Abstract

A method and apparatus for editing a source video that has already been taken to stabilize images in the video. To eliminate jerky motion from a video, changes in shots are first detected. Then, any jerkiness within the video of that shot is classified and the video is segmented further into smaller segments based on this classification. The jerkiness within the selected segments is removed. The corrected shot, comprising a plurality of frames, is then added to the preceding shot until all shots of the video have been appropriately corrected for jerkiness. To help the user identify the shots being edited, keyframes or snapshots of the shots are displayed, thereby allowing the user to decide whether processing of the shot is desired and which shots should be incorporated into the final video.

Dependent claims

A method for editing a source video signal comprising:

receiving the source video signal;
analyzing by a data processor of the source video to identify a shot in the source video signal, a shot in the source video being delimited as between two instances when a frame of the source video signal is substantially different from its immediately preceding frame;
analyzing by a data processor of the shot to identify any jerky image motion during the shot;
dividing the shot into a plurality of segments until each segment has only a single type of identified jerky motion;
classifying by a data processor of the identified jerky motion as one of a plurality of types of jerky motion, one type being that there is no jerky motion;
and
stabilizing the classified shot taking into account the classified type of jerky motion, such stabilizing being sufficient to generate a corrected shot output video signal in which the jerky motion is substantially removed from the shot in the source video signal.

An apparatus for editing a source video comprising:

receiving means for receiving the source video signal;
a processor for analyzing the source video to identify a shot in the source video signal, a shot in the source video being delimited as between two instances when a frame of the source video signal is substantially different from its immediately preceding frame, for analyzing the shot to identify any jerky image motion during the shot, for dividing the shot into a plurality of segments until each segment has only one identified type of jerky motion and for classifying the identified jerky motion as one of a plurality of types of jerky motion, one type being that there is no jerky motion, the processor generating a signal indicative of the classified type of jerky motion;
and
a video stabilizer receiving the classified shot and the signal indicative of the classified type of jerky motion, the video stabilizer employing the signal from the processor to stabilize the classified shot taking into account the classified type of jerky motion, such stabilizing being sufficient to generate a corrected shot output video signal in which the jerky motion is substantially removed from the shot in the source video signal.
