Our recent work on self-supervised learning and unsupervised domain adaptation for heterogeneous medical image segmentation is now available on arXiv: MAPSeg: Unified Unsupervised Domain Adaptation for Heterogeneous Medical Image Segmentation Based on 3D Masked Autoencoding and Pseudo-Labeling. MAPSeg is the first unified UDA framework that works for centralized, federated, and test-time UDA.
