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.

Test Sequences

The following zip-file contains four test sequences, along with ground truth motion fields and masks that identify regions where foreground and background texture information blends together (TB) because of motion blur: Download

Please refer to the included ReadMe.txt to see how to properly read in the motion fields.

If you are using these sequences in your work, please cite our work [1].
