Abstract

This paper proposes a warping-based motion compensation technique for video coding, which adaptively selects the translation-based and warping-based compensation for triangular patches formed on a target frame. Over-all MC efficiency is improved by introducing several techniques employed in HEVC, e.g., recursive patch partitioning, differential MV coding, and merge mode. In addition to these, a partial merge mode is newly introduced to further improve the MC efficiency. The advantage of the proposed technique is demonstrated by comparing it with an existing affine-based MC technique.
