摘要:

病变区域的精确分割对于优化其治疗是重要的。深度学习使得使用注释数据检测和分割病变区域成为可能。然而,在医学领域获得精确注释的数据是非常具有挑战性的。此外,标记的不确定性和不精确性使得分割结果不可靠。在本文中,我们解决了不确定的边界问题,一个新的证据神经网络与信息融合策略,和稀缺的注释数据的半监督学习。实验结果表明,我们的建议有更好的性能比国家的最先进的方法。

英文摘要:

Precise segmentation of a lesion area is important for optimizing its treatment. Deep learning makes it possible to detect and segment a lesion field using annotated data. However, obtaining precisely annotated data is very challenging in the medical domain. Moreover, labeling uncertainty and imprecision make segmentation results unreliable. In this paper, we address the uncertain boundary problem by a new evidential neural network with an information fusion strategy, and the scarcity of annotated data by semi-supervised learning. Experimental results show that our proposal has better performance than state-of-the-art methods.
