Medical image segmentation has been widely recognized as a pivot procedure
for clinical diagnosis, analysis, and treatment planning. However, the
laborious and expensive annotation process lags down the speed of further
advances. Contrastive learning-based weight pre-training provides an
alternative by leveraging unlabeled data to learn a good representation. In
this paper, we investigate how contrastive learning benefits the general
supervised medical segmentation tasks. To this end, patch-dragsaw contrastive
regularization (PDCR) is proposed to perform patch-level tugging and repulsing
with the …
