In recent video compression standards only translational motion is accurately compensated, constraining any higher order motion to be approximated by being split into smaller translational units. The objective of this paper is to improve the coding efficiency for video sequences containing complex motion.Various higher order motion models are considered and(More)
While the translational motion model remains predominant in motion compensation, better coding efficiency can be achieved by applying a higher order motion model in cases of non-translationally moving video content. But so far, temporal motion vector prediction has not been fully optimized in case of higher order motion compensation. In particular, if the(More)
Conventionally, complex motion in video sequences is approximated by smaller block units in order to be representable by a translational motion model. This approximation results in a fine block partitioning and a high prediction error, both at cost of more data rate than potentially necessary. A worthwhile data reduction has been shown to be achievable by(More)
