Abstract:
We propose a method for semantic segmentation in unsupervised domain adaptation (UDA) setting. We particularly examine the domain gap between spatial-class distributions and propose to align the local distributions of the segmentation predictions. Despite its simplicity, the proposed method achieves state-of-the-art results in UDA segmentation benchmarks.
