“…However, training an existing few-shot semantic segmentation (FSS) model for medical imaging has not had much success in the past, as most of FSS methods rely on a large training dataset with many annotated training classes to avoid overfitting [14,15,16,17,18,19,20,21,17,22,23,24,25]. In order to bypass this unmet need of annotation, we propose to train an FSS model on unlabeled images instead via self-supervised learning, an unsupervised technique that learns generalizable image representations by solving a carefully designed task [26,27,28,29,30,31,32,33].…”
