A Signal Adaptive Diffusion Filter for Video Coding Using Directional Total Variation

In this paper we combine state of the art video compression with inpainting methods. We introduce a new signal adaptive method to filter the predictions of a hybrid video codec using a constrained optimization approach. The filter is embedded into the framework of HEVC. The efficiency of the HEVC video codec is improved by up to -6.14% Bj Ø ntegaard delta (BD) rate for All Intra.
