The latest video coding standard HEVC has already improved 40% coding efficiency than H.264/AVC, but it still follows the hybrid coding structure with the translational motion compensation scheme. In this paper, an affine motion representation is described first. The proposed algorithms to improve the motion vector coding for Affine SKIP/MERGE modes are(More)
In this paper, we study a simplified affine motion model based coding framework to overcome the limitation of translational motion model and maintain low computational complexity. The proposed framework mainly has three key contributions. First, we propose to reduce the number of affine motion parameters from 6 to 4. The proposed four-parameter affine(More)
