PCLMix: Weakly Supervised Medical Image Segmentation via Pixel-Level Contrastive Learning and Dynamic Mix Augmentation

1 code implementation10 May 2024 Yu Lei, Haolun Luo, Lituan Wang, Zhenwei Zhang, Lei Zhang

In weakly supervised medical image segmentation, the absence of structural priors and the discreteness of class feature distribution present a challenge, i. e., how to accurately propagate supervision signals from local to global regions without excessively spreading them to other irrelevant regions?

Auto Machine Learning for Medical Image Analysis by Unifying the Search on Data Augmentation and Neural Architecture

no code implementations21 Jul 2022 Jianwei Zhang, Dong Li, Lituan Wang, Lei Zhang

To address the problem, an improved augmentation search strategy, named Augmented Density Matching, was proposed by randomly sampling policies from a prior distribution for training.
