| Abstract: |
Video codecs are primarily designed assuming that rigid, block-based, two-dimensional displacements are suitable models to describe the motion taking place in a scene. However, translational models are not sufficient to handle real world motion types such as camera zoom, shake, pan, shearing or changes in aspect ratio. We present here a region-based inter-prediction scheme to compensate such motion. The proposed mode is able to estimate multiple homography models in order to predict complex scene motion. We also introduce an affine photometric correction to each geometric model. Experiments on targeted sequences with complex motion demonstrate the efficiency of the proposed approach compared to the state-of-the-art HEVC video codec. |
