基于预测的视频对象发现自监督

Self-Supervision by Prediction for Object Discovery in Videos

EPFL(洛桑联邦理工学院)

Beril Besbinar, Pascal Frossard

摘要:

尽管深度学习算法取得了不可阻挡的成功,但它们仍然严重依赖于注释数据。另一方面,无监督设置带来了许多挑战,特别是在不同场景中确定正确的归纳偏差。一种可扩展的解决方案是通过利用部分输入数据使模型为自己生成监督,这被称为自监督学习。在本文中,我们使用的预测任务作为自我监督,并建立了一个新的对象为中心的图像序列表示模型。除了解开对象和运动动态的概念,我们的组成结构明确地处理遮挡和inpaints推断的对象和背景的预测帧的组成。借助于辅助损失函数,可以促进空间和时间一致的对象表示,我们的自监督框架可以在没有任何手动注释或预训练网络的帮助下进行训练。初步实验证实,所提出的管道是一个有前途的一步,以对象为中心的视频预测。

英文摘要:

Despite their irresistible success, deep learning algorithms still heavily rely on annotated data. On the other hand, unsupervised settings pose many challenges, especially about determining the right inductive bias in diverse scenarios. One scalable solution is to make the model generate the supervision for itself by leveraging some part of the input data, which is known as self-supervised learning. In this paper, we use the prediction task as self-supervision and build a novel object-centric model for image sequence representation. In addition to disentangling the notion of objects and the motion dynamics, our compositional structure explicitly handles occlusion and inpaints inferred objects and background for the composition of the predicted frame. With the aid of auxiliary loss functions that promote spatially and temporally consistent object representations, our self-supervised framework can be trained without the help of any manual annotation or pretrained network. Initial experiments confirm that the proposed pipeline is a promising step towards object-centric video prediction.
