Leveraging Category Information for Single-Frame Visual Sound Source Separation

Tampere University(坦佩雷大学)

Lingyu Zhu, Esa Rahtu

摘要:

视觉声音声源分离的目的是在视觉线索存在的情况下从给定的声音混合中识别声音分量。先前的工作已经展示了令人印象深刻的结果,但是以大型多级架构和复杂的数据表示(例如,光流轨迹)为代价。相比之下,我们研究简单而有效的模型,只使用一个单一的视频帧的视觉声音分离。此外,我们的模型是能够利用的信息的声源类别的分离过程中。为此,我们提出了两个模型,其中我们假设i)类别标签在训练时可用,或者ii)我们知道训练样本对是否来自相同或不同的类别。MUSIC数据集的实验表明,我们的模型获得了相当或更好的性能相比,最近的几个基线方法。代码可在https://github.com/ly-zhu/Leveraging-Category-Information-for-Single-Frame-Visual-Sound-Source-Separation上获得

英文摘要:

Visual sound source separation aims at identifying sound components from a given sound mixture with the presence of visual cues. Prior works have demonstrated impressive results, but with the expense of large multi-stage architectures and complex data representations (e.g. optical flow trajectories). In contrast, we study simple yet efficient models for visual sound separation using only a single video frame. Furthermore, our models are able to exploit the information of the sound source category in the separation process. To this end, we propose two models where we assume that i) the category labels are available at the training time, or ii) we know if the training sample pairs are from the same or different category. The experiments with the MUSIC dataset show that our model obtains comparable or better performance compared to several recent baseline methods. The code is available at https://github.com/ly-zhu/Leveraging-Category-Information-for-Single-Frame-Visual-Sound-Source-Separation
