| 摘要 |
The invention relates to a method, performed by a computer, for processing a video sequence comprising a reference frame, wherein, for each current frame of the video sequence, the method comprises determining a motion field between a current frame and a reference frame and a quality metric representative of the quality of the determined motion field from determined motion field. In the case where said quality metric is below a quality threshold, the method further comprises selecting a new reference frame among a group of previous current frames such that the quality metric of a previously generated motion field between the new reference frame and the reference frame is above the quality threshold, and iterating the determining of the motion field between current frame and reference frame by determining a motion field between current frame and new reference frame and concatenating the determined motion field between current frame and new reference frame with previously generated motion field between new reference frame and reference frame. |
