• Abstract summary: We introduce an unsupervised domain adaptation method built on the foundation of faster-RCNN to prevent drops in performance due to domain shift. We also introduce a family of adaptation layers that leverage the squeeze excitation mechanism called SE Adaptors to improve domain attention. Finally, we incorporate a center loss in the instance and image level representations to improve the intra-class variance.

• Abstract: Despite growing interest in object detection, very few works address the extremely practical problem of cross-domain robustness especially for automative applications. In order to prevent drops in performance due to domain shift, we introduce an unsupervised domain adaptation method built on the foundation of faster-RCNN with two domain adaptation components addressing the shift at the instance and image levels respectively and apply a consistency regularization between them. We also introduce a family of adaptation layers that leverage the squeeze excitation mechanism called SE Adaptors to improve domain attention and thus improves performance without any prior requirement of knowledge of the new target domain. Finally, we incorporate a center loss in the instance and image level representations to improve the intra-class variance. We report all results with Cityscapes as our source domain and Foggy Cityscapes as the target domain outperforming previous baselines.

  Key challenge in panoptic domain adaptation is reducing the domain gap between a labeled source and an unlabeled target domain. We focus on incorporating instance-level adaptation via a novel cross-domain mixing strategy IMix. We present an end-to-end model incorporating these two mechanisms called LIDAPS, achieving state-of-the-art results on all popular panoptic UDA benchmarks.
