METHOD AND DEVICE FOR GENERATING A MOTION FIELD FOR A VIDEO SEQUENCE
摘要:
The invention relates to a method for generating a motion field between a current frame and a reference frame belonging to a video sequence from an input set of elementary motion fields. The method comprises the following steps performed for each pixel belonging to said current frame: determining a plurality of candidate motion vectors between the current frame and the reference frame wherein each candidate motion vector is the result of the sum of a first motion vector between the current frame and an intermediary frame belonging to the video sequence and of a second motion vector between the intermediary frame and the reference frame; and selecting a motion vector among candidate motion vectors. The method is remarkable in that the first motion vector belongs to the input set of elementary motion fields and the second motion vector belongs to a set of previously selected motion vectors for other current frames of the video sequence.
