MdVRNet: Deep Video Restoration under Multiple Distortions

Abstract

Video restoration techniques aim to remove artifacts, such as noise, blur, and compression, introduced at various levels within and outside the camera imaging pipeline during video acquisition. Although excellent results can be achieved by considering one artifact at a time, in real applications a given video sequence can be affected by multiple artifacts, whose appearance is mutually influenced. In this paper, we present Multi-distorted Video Restoration Network (MdVRNet), a deep neural network specifically designed to handle multiple distortions simultaneously. Our model includes an original Distortion Parameter Estimation sub-Network (DPEN) to automatically infer the intensity of various types of distortions affecting the input sequence, novel Multi-scale Restoration Blocks (MRB) to extract complementary features at different scales using two parallel streams, and implements a two-stage restoration process to focus on different levels of detail. We document the accuracy of the DPEN module in estimating the intensity of multiple distortions, and present an ablation study that quantifies the impact of the DPEN and MRB modules. Finally, we show the advantages of the proposed MdVRNet in a direct comparison with another existing state-of-the-art approach for video restoration.
