摘要:

糖尿病视网膜病变(DR)的自动分级有助于患者和医生的医疗诊断。现有的研究将DR分级作为一个图像分类问题。由于DR的阶段/类别彼此相关,因此无法通过单一热门标签明确描述不同类别之间的关系,因为它是由具有不同结局的不同医生凭经验估计的。这种类别相关性限制了现有网络实现有效分类。在本文中,我们提出了一个图剩余rE-排名网络(绿色),引入一个类依赖先验到原来的图像分类网络。类依赖先验由具有邻接矩阵的图卷积网络表示。该先验通过以残差聚合方式对分类结果重新排序来增强图像分类流水线。在标准基准测试上的实验表明,GREEN的性能优于最先进的方法。

英文摘要:

The automatic grading of diabetic retinopathy (DR) facilitates medical diagnosis for both patients and physicians. Existing researches formulate DR grading as an image classification problem. As the stages/categories of DR correlate with each other, the relationship between different classes cannot be explicitly described via a one-hot label because it is empirically estimated by different physicians with different outcomes. This class correlation limits existing networks to achieve effective classification. In this paper, we propose a Graph REsidual rE-ranking Network (GREEN) to introduce a class dependency prior into the original image classification network. The class dependency prior is represented by a graph convolutional network with an adjacency matrix. This prior augments image classification pipeline by re-ranking classification results in a residual aggregation manner. Experiments on the standard benchmarks have shown that GREEN performs favorably against state-of-the-art approaches.
