Paper Abstract

In this and an accompanying paper in the same proceedings a hierarchical video coding scheme is presented which is designed mainly for video communications at very low bit rates and therefore based on the hybrid coding principle. Both the displacement vector field and the displaced frame differences are decomposed into a Laplacian-type pyramid, and these pyramids are encoded in an embedded fashion using zero-trees and conditioning contexts, respectively. The focus of this paper lies on the motion estimation and the design of the motion vector field coding. Especially, the aspect of estimating and coding vector fields of different resolution is investigated to achieve optimal coding efficiency in coding situations, where there is not enough data rate available to code higher resolution vector fields completely.
