HIGH SPEED BMA FOR Bi-DIRECTIONAL MOVING VECTOR ESTIMATION

There is provided a high speed matching algorithm capable of effectively predicting a bidirectional motion vector in a motion compensated prediction algorithm in which unidirectional prediction picture and bidirectional prediction picture are applicably used. The algorithm concurrently improves accuracy in predicting bidirectional motion vector and calculated amount using time space interrelation of the motion vector and constant speed model for motion displacement.
