During the past decades, videos have already taken the main part of our daily entertainment. When transmitting videos over the bandwidth-limited Internet, video compression should be applied to significantly save the coding bit-rate. Lossy codec technologies and standards for videos, such as the well-known HEVC, have achieved an impressive coding efficiency. However, due to the compromise to lower the bit-rate, the distortions are ineluctably induced in the codec. For example, there are visible discontinuities at block boundaries in the decoded images, which are known as blocking artifacts. Other artifacts may include blurring, ringing, color bias, etc. These compression artifacts may cause severe degradation in the visual quality at the decoder side. Therefore, how to reduce the compression artifacts has attracted more and more attention in recent years.

Abstract:
We proposed a residual-based post-processing for high-efficiency video coding (HEVC). Based on the proposed network, residual-based video restoration network (residual-VRN), the decoded image quality, has been improved significantly. We experimentally verified the superiority of the method.
