A method is provided for estimating motion vectors providing image displacements between reference images (IN) in a sequence of digital video images and intermediate image (BN) falling between reference images in sequence. Motion vectors are derived to estimate a prediction (PN) of one reference image (IN) from another in the sequence. Motion vectors are then derived for generating predictions of each intermediate image (BN) between two reference images (IN) in the sequence from one of the two reference images (IN) or their predictions (PN). From these estimated vectors further vectors are derived for deriving a prediction of each intermediate image (BN) from the other one of the two reference images or their predictions which it falls between. |
