Abstract

As we have seen in Chap.  2, existing video codecs anchor motion information at the frame that is to be predicted. In this thesis, we part from this conventional wisdom and investigate new motion anchoring strategies for highly scalable video compression, where motion fields are anchored at reference frames instead. As it turns out, this has a number of advantages over the traditional way of anchoring motion at reference frames. One of the main challenges using such a reference-based motion anchoring is that in order to be used for predicting the target frames, motion fields need to be warped to the target frames. This process leads to holes in disoccluding regions, as well as double mappings in the warped motion fields.
