摘要:

作为递归神经网络层的条件随机场是最近提出的一种算法,旨在置于现有的全卷积神经网络之上,以提高语义分割的质量。在本文中,我们测试这种算法,这是改善语义分割的2D RGB图像,是能够提高分割质量的3D多模态医学图像。我们开发了一个实现的算法,适用于任何数量的空间维度,输入/输出图像通道,和参考图像通道。据我们所知,这是第一个公开的这种实现。我们用两个不同的3D医学成像数据集测试了该算法,我们得出的结论是,观察到的性能差异在统计学上不显著。最后,在本文的讨论部分,我们将探讨为什么这种技术从自然图像到医学图像的转换效果很差的原因。

英文摘要:

The Conditional Random Field as a Recurrent Neural Network layer is a recently proposed algorithm meant to be placed on top of an existing Fully-Convolutional Neural Network to improve the quality of semantic segmentation. In this paper, we test whether this algorithm, which was shown to improve semantic segmentation for 2D RGB images, is able to improve segmentation quality for 3D multi-modal medical images. We developed an implementation of the algorithm which works for any number of spatial dimensions, input/output image channels, and reference image channels. As far as we know this is the first publicly available implementation of this sort. We tested the algorithm with two distinct 3D medical imaging datasets, we concluded that the performance differences observed were not statistically significant. Finally, in the discussion section of the paper, we go into the reasons as to why this technique transfers poorly from natural images to medical images.
