Abstract

Computer Vision has become increasingly capable of representing the 3D world, given large sets of dense and complete observations, such as images or 3D scans. However, in comparison with humans, we still lack an important ability: deriving 3D representations from just a few, incomplete 2D observations. Replicating this ability might be the next important step towards a general vision system. A key aspect of the human abilities is that observations are complemented by previously learned information: the world is not only sensed - to a large degree it is inferred. The common way to approach this task with deep learning are data priors, which capture information present in large datasets and which are used to perform inference from novel observations.

This talk will discuss 3D data priors and their important connection to 3D representations. Choosing the right representation, we can have abstract control over which information is learned from data and how we can use it during inference, which leads to more effective solutions than simply learning everything end-to-end. Thus, the focus of my research and this talk will be on representations with important properties, such as data efficiency and useful equi- and invariances, which enable the formulation of sophisticated, task-specific data priors. These presented concepts are showcased on examples from my and collaborating groups, e.g., as data priors for reconstructing objects or object interaction sequences from incomplete observations.
