Motion blur modelling for hierarchically anchored motion with discontinuities

We have previously proposed a scheme for representing motion with motion discontinuities which has beneficial properties in terms of compactness (efficiency) and scalability. This so-called BIHA scheme has applications in video coding as well as temporal frame interpolation. In both cases, modelling of motion discontinuities has proven to be valuable. In these earlier works, we have ignored effects of motion blur, which can result in artificial sharp transitions of texture information at moving object boundaries. In this paper, we extend the BIHA framework to account for motion blur. Experimental results show significant improvements over the original BIHA scheme in texture blending regions, resulting in more visually pleasing predictions, as well as better rate-distortion performance.
