Leveraging Video Coding Knowledge for Deep Video Enhancement
This work addresses video quality enhancement for compressed videos, but it is incremental as it builds upon an existing state-of-the-art method.
The study tackled the problem of compressed video enhancement by exploiting motion characteristics and hierarchical coding structure, achieving improvements in quantitative metrics and visual quality over BasicVSR++ in the NTIRE22 challenge.
Recent advancements in deep learning techniques have significantly improved the quality of compressed videos. However, previous approaches have not fully exploited the motion characteristics of compressed videos, such as the drastic change in motion between video contents and the hierarchical coding structure of the compressed video. This study proposes a novel framework that leverages the low-delay configuration of video compression to enhance the existing state-of-the-art method, BasicVSR++. We incorporate a context-adaptive video fusion method to enhance the final quality of compressed videos. The proposed approach has been evaluated in the NTIRE22 challenge, a benchmark for video restoration and enhancement, and achieved improvements in both quantitative metrics and visual quality compared to the previous method.
