摘要:

损失函数是基于深度学习的医学图像分割方法的关键要素之一。在现有文献中已经提出了许多损失函数,但是单独研究或仅研究很少的其他损失。在本文中,我们提出了一个系统的分类,现有的损失函数分为四个有意义的类别。这有助于揭示它们之间的联系和基本相似之处。此外,我们探讨了传统的基于区域的损失函数和最近的基于边界的损失函数之间的关系。这些损失函数的PyTorch实现可在\url{https://github.com/JunMa11/SegLoss}上公开获得。

英文摘要:

Loss functions are one of the crucial ingredients in deep learning-based medical image segmentation methods. Many loss functions have been proposed in existing literature, but are studied separately or only investigated with few other losses. In this paper, we present a systematic taxonomy to sort existing loss functions into four meaningful categories. This helps to reveal links and fundamental similarities between them. Moreover, we explore the relationship between the traditional region-based and the more recent boundary-based loss functions. The PyTorch implementations of these loss functions are publicly available at \url{https://github.com/JunMa11/SegLoss}.
