针对EM线粒体分割研究可复现性不足的问题,本文统一预处理、后处理与超参数扫描,系统评估2D/3D U-Net类架构,提出在EPFL Hippocampus、Lucchi++和Kasthuri++上达到或超越现有方法的稳定配置并公开代码。

摘要:

电子显微镜(EM)能够识别线粒体等细胞器,为临床和科学研究提供洞见。近年来,许多新颖的深度学习架构相继发表,并称在公开线粒体分割数据集上相较以往方法取得了更优性能,甚至达到人类水平的准确率。遗憾的是,其中许多论文既未公开代码,也未公开完整训练细节来支撑所得结果,从而造成可复现性问题以及令人怀疑的模型比较。为此,我们遵循近期关于报告实验结果的最佳实践规范,对用于EM体数据中线粒体分割的最先进深度学习架构进行了广泛研究,并评估了该任务中2D和3D U-Net类模型不同变体对性能的影响。为更好地理解每个组件的贡献,我们为每种方法实现并测试了一组共同的预处理和后处理操作。此外,我们对所有架构进行了详尽的超参数值扫描,并且每种配置都多次运行,以报告评估指标的均值和标准差。利用这一方法,我们发现了非常稳定的架构和超参数配置,它们在著名的EPFL Hippocampus线粒体分割数据集上持续取得最先进结果。此外,我们还在另外两个可用数据集Lucchi++和Kasthai++上对所提出模型进行了基准测试,模型在这些数据集上优于所有以往工作。本研究产生的代码及其文档均已公开。

英文摘要:

Electron microscopy (EM) allows the identification of intracellular organelles such as mitochondria, providing insights for clinical and scientific studies. In recent years, a number of novel deep learning architectures have been published reporting superior performance, or even human-level accuracy, compared to previous approaches on public mitochondria segmentation datasets. Unfortunately, many of these publications do not make neither the code nor the full training details public to support the results obtained, leading to reproducibility issues and dubious model comparisons. For that reason, and following a recent code of best practices for reporting experimental results, we present an extensive study of the state-of-the-art deep learning architectures for the segmentation of mitochondria on EM volumes, and evaluate the impact in performance of different variations of 2D and 3D U-Net-like models for this task. To better understand the contribution of each component, a common set of pre- and post-processing operations has been implemented and tested with each approach. Moreover, an exhaustive sweep of hyperparameters values for all architectures have been performed and each configuration has been run multiple times to report the mean and standard deviation values of the evaluation metrics. Using this methodology, we found very stable architectures and hyperparameter configurations that consistently obtain state-of-the-art results in the well-known EPFL Hippocampus mitochondria segmentation dataset. Furthermore, we have benchmarked our proposed models on two other available datasets, Lucchi++ and Kasthuri++, where they outperform all previous works. The code derived from this research and its documentation are publicly available.
