A Critical Look at Classic Test-Time Adaptation Methods in Semantic Segmentation

no code implementations9 Oct 2023 Chang'an Yi, Haotian Chen, Yifan Zhang, Yonghui Xu, Lizhen Cui

This pronounced emphasis on classification might lead numerous newcomers and engineers to mistakenly assume that classic TTA methods designed for classification can be directly applied to segmentation.

ATPL: Mutually enhanced adversarial training and pseudo labeling for unsupervised domain adaptation

no code implementations Knowledge-Based Systems 2022 Changan Yi, Haotian Chen, Yonghui Xu, Yong liu, Lei Jiang, Haishu Tan

Accordingly, ATPL will use the pseudo-labeled information to improve the adversarial training process, which can guarantee the feature transferability by generating adversarial data to fill in the domain gap.
