Deep learning-based approaches achieve state-of-the-art performance in the majority of image segmentation benchmarks. However, training of such models requires a sizable amount of manual annotations. In order to reduce this effort, we propose a method based on conditional Generative Adversarial Network (cGAN), which addresses segmentation in a semi-supervised setup and in a human-in-the-loop fashion. More specifically, we use the discriminator to identify unreliable slices for which expert annotation is required and use the generator in the GAN to synthesize segmentations on unlabeled data for which the model is confident. The quantitative results on a conventional standard benchmark show that our method is comparable with the state-of-the-art fully supervised methods in slice-level evaluation requiring far less annotated data.

最近,深度神经网络在注释良好的数据集中表现出与董事会认证的眼科医生相当甚至更好的性能。然而,视网膜成像设备的多样性带来了一个重大挑战:域转移,这导致在将深度学习模型应用于新的测试域时性能下降。在本文中,我们提出了一种新的无监督域自适应框架,称为协作特征集成自适应(CFEA),以有效地克服这一挑战。我们提出的CFEA是一个交互式的范例,通过对抗学习和集成权重呈现出一种精致的协作适应。特别是,我们同时实现了域不变性,并保持了历史预测的指数移动平均值,这通过在训练期间集成权重来实现对未标记数据的更好预测。在不注释来自目标域的任何样本的情况下,编码器和解码器层中的多个对抗性损失引导域不变特征的提取,以混淆域分类器,同时有利于平滑权重的集成。综合实验结果表明,我们的CFEA模型可以克服性能下降,并优于国家的最先进的方法在分割视网膜视盘和杯眼底图像。\textit{Code is available at \url{https://github.com/cswin/AWC}}。

目的:卷积神经网络(CNN)在自动心脏磁共振图像分割中表现出了良好的前景。然而,当在大型真实世界数据集中使用CNN时,量化分割不确定性并识别可能存在问题的分割是很重要的。在这项工作中,我们对贝叶斯和非贝叶斯方法进行了系统的研究,用于估计分割神经网络中的不确定性。研究方法:我们通过Backprop,Monte Carlo Dropout,Deep Ensembles和Stochastic Segmentation Networks在分割精度,概率校准,分布外图像的不确定性和分割质量控制方面评估了贝叶斯。结果:我们观察到,除了具有严重噪声和模糊失真的图像外,深度集成优于其他方法。我们证明了贝叶斯反向传播对噪声失真更鲁棒,而随机分割网络对模糊失真更有抵抗力。对于分割质量控制,我们表明,分割不确定性与所有方法的分割精度相关。通过合并不确定性估计,我们能够通过标记31 - 48%的最不确定分割进行手动审查,将不良分割的百分比降低到5%,大大低于不使用神经网络不确定性的随机审查(审查所有图像的75 - 78%)。结论:这项工作提供了一个全面的评估不确定性估计方法,并表明,深度集成优于其他方法在大多数情况下。重要性:神经网络不确定性测量可以帮助识别潜在的不准确分割,并提醒用户进行手动审查。
