摘要:

本文研究了糖尿病视网膜病变(DR)分级的领域自适应问题。我们学习不变的目标域特征定义了一种新的自我监督任务的基础上视网膜血管图像重建,医学领域知识的启发。然后,提供了当前最先进的无监督领域自适应方法在DR问题上的基准。可以看出,我们的方法优于现有的域自适应策略。此外,当利用目标域中的整个训练数据时,我们能够通过应用标准网络架构和使用图像级标签在最终分类精度上与几种最先进的方法竞争。

英文摘要:

This paper investigates the problem of domain adaptation for diabetic retinopathy (DR) grading. We learn invariant target-domain features by defining a novel self-supervised task based on retinal vessel image reconstructions, inspired by medical domain knowledge. Then, a benchmark of current state-of-the-art unsupervised domain adaptation methods on the DR problem is provided. It can be shown that our approach outperforms existing domain adaption strategies. Furthermore, when utilizing entire training data in the target domain, we are able to compete with several state-of-the-art approaches in final classification accuracy just by applying standard network architectures and using image-level labels.
