Video clip selection via interaction with a hierarchic video segmentation

摘要

A video segment selection method and system that determines a set of segment boundaries in the video, determines a segment boundary tree from the set of segment boundaries, presents a video timeline that shows a plurality of segment boundaries from a first level of the segment boundary tree, receives a first selection point and a first request to change a zoom factor for an interval of the video timeline around the first selection point, and, in response to the first request to change the zoom factor for the interval of the video timeline around the first selection point, updates the video timeline in the interval around the first selection point to show a plurality of segment boundaries from a second level of the segment boundary tree corresponding to the changed zoom factor.

1. A method for selecting a segment of a video, the method comprising:
determining, using a processor, a set of segment boundaries in the video; determining a segment boundary tree from the set of segment boundaries; presenting a video timeline that shows a plurality of segment boundaries from a first level of the segment boundary tree; receiving a first selection point and a first request to change a zoom factor for an interval of the video timeline around the first selection point; and in response to the first request to change the zoom factor for the interval of the video timeline around the first selection point, updating the video timeline in the interval around the first selection point to show a plurality of segment boundaries from a second level of the segment boundary tree corresponding to the changed zoom factor.
