Abstract
A method of approximating a motion vector for an image block, the method comprising retrieving motion vectors for neighbouring blocks, identifying a predominant value of at least one motion vector characteristic from the motion vectors for the neighbouring blocks, selecting those motion vectors for the neighbouring blocks which have a value which is the same or similar to said predominant value to form a group, and deriving an approximation for the motion vector for the image block from the selected group of motion vectors.
