Forward-Only Hierarchical Anchoring (FOHA) of Motion

  • Dominic Rüfenacht
Part of the Springer Theses book series (Springer Theses)


The bidirectional hierarchical anchoring (BIHA) of motion presented in the last chapter constitutes a fundamental change in the way motion is anchored and employed in a video compression system. Anchoring motion at reference-frames might appear counter-intuitive, since the motion information has to be mapped to target frames in order to serve as prediction reference. However, as shown in the last two chapters, this change of motion anchoring has a number of key advantages over the traditional anchoring of motion. First, motion information at finer temporal levels can be “recycled” from coarser levels, via the motion scaling operation. Second, during the motion mapping process, disoccluded regions are readily observed; this valuable information has to be explicitly communicated in a traditional anchoring scheme.
