Title
Structure-Guided Deep Video Inpainting
Abstract
A fundamental challenge in video inpainting is the difficulty of generating video contents with fine details, while keeping spatio-temporal coherence in the missing region. Recent studies focus on synthesizing temporally smooth pixels by exploiting the flow information, while ignoring maintaining the semantic structural coherence between frames. This makes them suffer from over-smoothing and blurry contours, which significantly reduce the visual quality of inpainting results. To address this issue, we present a novel structure-guided video inpainting approach that enhances temporal structure coherence to improve video inpainting results. In contrast to directly synthesizing the missing pixel colors, we first complete edges in the missing regions to depict scene structures and object shapes via an edge inpainting network with 3D convolutions. Then, we replenish textures using a coarse-to-fine synthesis network with a structure attention module (SAM), under the guidance of the synthesized edges. Specifically, our SAM is designed to model the semantic correlation between video textures and structural edges to generate more realistic content. Besides, motion flows between neighboring frames are employed to enhance temporal consistency for self-supervision during training the edge inpainting and texture inpainting modules. Consequently, the inpainting results using our approach are visually pleasing with fine details and temporal coherence. Experiments on the YouTubeVOS, DAVIS, and 300VW datasets show that our method obtains state-of-the-art performance under diverse video inpainting settings.
