Based on these 2D annotations, we automatically reconstruct 3D plane equations for the structural elements and their spatial extent in the scene, and connect adjacent elements at the appropriate contact edges.

We propose a method for annotating videos of complex multi-object scenes with a globally-consistent 3D representation of the objects.

We propose a transformer-based neural network architecture for multi-object 3D reconstruction from RGB videos.

We leverage a key observation: propagation from labeled to unlabeled pixels does not necessarily require class-specific knowledge, but can be done purely based on appearance similarity within an image.

Furthermore, we adapt our model to address the harder task of reconstructing multiple objects from a single image.

Flow-based generative models have highly desirable properties like exact log-likelihood evaluation and exact latent-variable inference, however they are still in their infancy and have not received as much attention as alternative generative models.

Manually annotating object segmentation masks is very time consuming.

We present Open Images V4, a dataset of 9. 2M images with unified annotations for image classification, object detection and visual relationship detection.

We propose to revisit knowledge transfer for training object detectors on target classes from weakly supervised training images, helped by a set of source classes with bounding-box annotations.
