Deformable Convolution Network based Invertibility-Driven Interpolation Filter for HEVC

Fractional-position motion compensation has been widely utilized in video coding standard to improve the inter prediction efficiency. In this paper, we study the three key components of the state-of-the-art method––Invertibility-driven Interpolation Filter (InvIF) and improve each of them to derive an Enhanced InvIF (EInvIF). Firstly, the deformable convolution layer is introduced to make the netw...
