Abstract: In one embodiment, a computing system may determine a view position, a view direction, and a time with respect to a scene. The system may access a spatiotemporal representation of the scene generated based on (1) a monocular video including images each capturing at least a portion of the scene at a corresponding time and (2) depth values of the portion of the scene captured by each image. The system may generate an image based on the view position, the view direction, the time, and the spatiotemporal representation. A pixel value of the image corresponding to the view position may be determined based on volume densities and color values at sampling locations along the view direction and at the time in the spatiotemporal representation. The system may output the image to the display, representing the scene at the time as viewed from the view position and in the view direction.

Abstract: Systems and methods for unsupervised representation learning by sorting sequences are provided. An unsupervised representation learning approach is provided which uses videos without semantic labels. The temporal coherence as a supervisory signal can be leveraged by formulating representation learning as a sequence sorting task. A plurality of temporally shuffled frames (i.e., in non-chronological order) can be used as inputs and a convolutional neural network can be trained to sort the shuffled sequences and to facilitate machine learning of features by the convolutional neural network. Features are extracted from all frame pairs and aggregated to predict the correct sequence order. As sorting shuffled image sequence requires an understanding of the statistical temporal structure of images, training with such a proxy task can allow a computer to learn rich and generalizable visual representations from digital images.
