摘要:

这项工作的目标是本地化的声源在视觉场景。现有的视听作品采用对比学习,通过将来自相同源的对应视听对分配为正,而将随机不匹配的对分配为负。然而,这些否定对可能包含语义匹配的视听信息。因此,这些语义相关的对,“硬阳性”,被错误地分组为阴性。我们的主要贡献是表明,硬阳性可以给相应的对类似的响应图。我们的方法将这些硬阳性添加到一个对比学习目标的反应地图直接。我们证明了我们的方法的有效性VGG-SS和SoundNet-Flickr测试集,表现出良好的性能,最先进的方法。

英文摘要:

The objective of this work is to localize the sound sources in visual scenes. Existing audio-visual works employ contrastive learning by assigning corresponding audio-visual pairs from the same source as positives while randomly mismatched pairs as negatives. However, these negative pairs may contain semantically matched audio-visual information. Thus, these semantically correlated pairs, "hard positives", are mistakenly grouped as negatives. Our key contribution is showing that hard positives can give similar response maps to the corresponding pairs. Our approach incorporates these hard positives by adding their response maps into a contrastive learning objective directly. We demonstrate the effectiveness of our approach on VGG-SS and SoundNet-Flickr test sets, showing favorable performance to the state-of-the-art methods.
