Method and apparatus for camera motion analysis in video

摘要

Embodiments disclose methods and apparatuses for camera motion analysis in a video, wherein one of the methods includes: analyzing, video segments with significant movement characteristics and video segments without any significant movement characteristic; for each segment without any significant movement characteristic, if a first motion type corresponding to a preceding neighboring video segment is different from a second motion type corresponding to a succeeding neighboring video segment, lowering detection criterions of the first type and the second type; judging whether the segment without any significant movement characteristic meets the lowered detection criterions; and merging the segment without any significant movement characteristic with a neighboring video segment according to the result of judgment. With the embodiments of the invention the motion type of a camera in the video can be detected more effectively and accurately, and the photographic intention of a user can be reflected more accurately.

主权项

1. A method for camera motion analysis in a video, comprising:
analyzing, from the video, video segments with significant movement characteristics and video segments without significant movement characteristics; lowering, for each video segment without significant movement characteristics, detection criterions of a first motion type and a second motion type when the first motion type corresponding to a preceding neighboring video segment is different from the second motion type corresponding to a succeeding neighboring video segment; judging whether the video segment without significant movement characteristics meet the lowered detection criterions; and merging the video segment without significant movement characteristics with one or more neighboring video segments according to a result of the judging.
