VIDEO PROCESSOR COMPRISING A MOTION ESTIMATOR OF THE RECURSIVE TYPE

摘要

A video processor comprises a motion estimator (ME) of the recursive type that establishes a motion vector field (MVF). The motion vector field (MVF) comprises respective motion vectors for respective spatial positions in a picture. A motion vector classifier (CLSF) classifies at least a portion of the respective motion vectors in the motion vector field (MVF). Accordingly, the motion vector classifier (CLSF) establishes one or more classes of motion vectors (MVC). A class representative generator (CRG) generates one or more class representing motion vectors (MVR). A class representing motion vector represents a particular class of motion vectors that the motion vector classifier (CLSF) has established. A motion vector generator (GEN) establishes a new motion vector (MV) for the motion vector field (MVF) on the basis of the one or more class representing motion vectors (MVR).
