Affinity Space Adaptation for Semantic Segmentation Across Domains

---

Pytorch implementation of the paper "Affinity Space Adaptation for Semantic Segmentation Across Domains", TIP, 2020. In this paper, we address the problem of unsupervised domain adaptation (UDA) in semantic segmentation, achieving the state-of-the-art performance on standard benchmarks.
