Humans are continuously exposed to a stream of visual data with a natural temporal structure. However, most successful computer vision algorithms work at image level, completely discarding the precious information carried by motion. In this paper, we claim that processing visual streams naturally leads to formulate the motion invariance principle, which enables the construction of a new theory of learning that originates from variational principles, just like in physics. Such principled approach is well suited for a discussion on a number of interesting questions that arise in vision, and it offers a well-posed computational scheme for the discovery of convolutional filters over the retina. Differently from traditional convolutional networks, which need massive supervision, the proposed theory offers a truly new scenario for the unsupervised processing of video signals, where features are extracted in a multi-layer architecture with motion invariance. While the theory enables the implementation of novel computer vision systems, it also sheds light on the role of information-based principles to drive possible biological solutions.

我们提出了一个简单而有效的自监督框架视听表示学习,本地化的声源在视频中。为了理解是什么使得能够学习有用的表示,我们系统地研究了数据增强的效果,并揭示了(1)数据增强的组合起着关键作用,即明确地鼓励视听表示对各种变换保持不变~({ \em变换不变性});(2)强制几何一致性实质上提高了学习表示的质量,即,检测到的声源应当遵循应用于输入视频帧的相同变换~({ \em变换等方差})。大量的实验表明,我们的模型显着优于以前的方法在两个声音定位基准,即,Flickr-SoundNet和VGG-Sound。此外,我们还评估了音频检索和跨模态检索任务。在这两种情况下,我们的自监督模型表现出优越的检索性能,甚至与音频检索中的监督方法竞争。这表明,所提出的框架学习强大的多模态表示,有利于声音的本地化和推广到进一步的应用。\textit{All codes will be available}。
