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)
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)
