Abstract
An interpolation method for coded motion information available to a video coder, comprising the steps of incorporating edge information derived from coded video frames to perform an edge-sensitive interpolation of coded motion vectors (“seeds”) in order to obtain a dense motion description.
Claims22
A method for processing encoded video data using coded block motion, said coded block motion being originally determined by a video encoder and recovered by decoding the encoded video data, the method comprising:
- deriving edge information from a decoded reference frame;
- determining motion seeds from the coded block motion to provide a sparse motion description;
- and
- performing an edge-sensitive interpolation of the motion seeds, to obtain a dense motion description.
