摘要:

在本文中,我们介绍了一个概念上简单的网络,用于生成判别性组织级分割掩模,用于乳腺癌诊断。我们的方法有效地分割乳腺活检图像中不同类型的组织,同时预测用于识别图像中重要区域的判别图。我们的网络Y-Net通过添加一个用于区分映射生成的并行分支和支持卷积块模块化来扩展和推广U-Net,这允许用户在不改变网络拓扑的情况下调整网络效率。Y-Net提供了最先进的分割精度,同时学习的参数比最接近的竞争对手少6.6倍。与最先进的诊断分类方法相比,Y-Net的判别分割模板增加了描述能力,使诊断分类准确率提高了7%。源代码可在https://sacmehta.github.io/YNet上获得。

英文摘要:

In this paper, we introduce a conceptually simple network for generating discriminative tissue-level segmentation masks for the purpose of breast cancer diagnosis. Our method efficiently segments different types of tissues in breast biopsy images while simultaneously predicting a discriminative map for identifying important areas in an image. Our network, Y-Net, extends and generalizes U-Net by adding a parallel branch for discriminative map generation and by supporting convolutional block modularity, which allows the user to adjust network efficiency without altering the network topology. Y-Net delivers state-of-the-art segmentation accuracy while learning 6.6x fewer parameters than its closest competitors. The addition of descriptive power from Y-Net's discriminative segmentation masks improve diagnostic classification accuracy by 7% over state-of-the-art methods for diagnostic classification.
