Video summarization compresses videos while preserving the most meaningful content for users. Many image-based works focus on how to effectively utilize video visual cues to choose keyframes. However, apart from visual content, videos also contain useful audio information. In this paper, we propose a novel attention-based audio-visual fusion framework which integrates the audio information with visual information. Our framework is composed of two key components: asymmetrical self-attention mechanism, and odd-even attention. The asymmetrical self-attention mechanism addresses the problem that visual information is more strongly related to video summarization than audio information. The odd-even attention focuses on alleviating the memory requirements. Besides, we create ViAu-SumMe, an audio-visual dataset, which is based on SumMe dataset. Experimental results on the dataset show that our proposed method outperforms the state-of-the-art methods.
