摘要：Aspects of the present invention are related to low complexity systems andmethods for nonlinear diffusion filtering of a motion-vector field. Local weights in thenonlinear diffusion filter may be data-adaptive, and, according to one aspect of the
present invention, may be determined such that spatial coherency may not be enforcedat object boundaries although the object boundaries have not been explicitly detected.Thus, the methods and systems of the present invention may smooth a motion-vectorfield without smoothing the motion-vector field across an object boundary. According toa second aspect of the present invention, motion vectors with a low confidence value maybe suppressed, while motion vectors with a high confidence value may be propagated.According to another aspect of the present invention, motion estimation methods andsystems may incorporate the methods and systems of the nonlinear diffusion filteringaccording to the present invention.
