Deep Video Inpainting Guided by Audio-Visual Self-Supervision
This work addresses video inpainting for multimedia applications by integrating audio cues, offering an incremental improvement over existing methods.
The paper tackles video inpainting by using audio-visual self-supervision to guide the process, resulting in improved restoration of video scenes, especially when sounding objects are partially blinded, as demonstrated in experiments.
Humans can easily imagine a scene from auditory information based on their prior knowledge of audio-visual events. In this paper, we mimic this innate human ability in deep learning models to improve the quality of video inpainting. To implement the prior knowledge, we first train the audio-visual network, which learns the correspondence between auditory and visual information. Then, the audio-visual network is employed as a guider that conveys the prior knowledge of audio-visual correspondence to the video inpainting network. This prior knowledge is transferred through our proposed two novel losses: audio-visual attention loss and audio-visual pseudo-class consistency loss. These two losses further improve the performance of the video inpainting by encouraging the inpainting result to have a high correspondence to its synchronized audio. Experimental results demonstrate that our proposed method can restore a wider domain of video scenes and is particularly effective when the sounding object in the scene is partially blinded.
