摘要:

本文介绍了用于病理分析的糖尿病足溃疡数据集(DFUC 2021),重点是感染和缺血。我们描述了DFUC 2021的数据准备,地面实况注释,数据整理和数据分析。DFUC 2021的最终版本包括15,683个DFU补丁,其中5,955个用于培训,5,734个用于测试,3,994个未标记的DFU补丁。地面实况标签有四个类别,即对照、感染、缺血和两种情况。我们使用图像哈希技术整理数据集,并使用UMAP投影分析可分性。我们在DFUC 2021上对深度学习的五个关键骨干进行了性能基准测试,即VGG 16,ResNet 101,InceptionV 3,DenseNet 121和EfficientNet。我们报告了这些关键骨架的优化结果与不同的策略。根据我们的观察,我们得出结论,具有数据增强和迁移学习的EfficientNetB 0为多类(4类)分类提供了最佳结果,宏观平均精度,召回率和F1分数分别为0.57,0.62和0.55。在缺血和感染识别方面,当进行一对多的训练时,EfficientNetB 0取得了与最先进水平相当的结果。最后,我们通过统计分析和Grad-CAM可视化来解释结果。

英文摘要:

This paper introduces the Diabetic Foot Ulcers dataset (DFUC2021) for analysis of pathology, focusing on infection and ischaemia. We describe the data preparation of DFUC2021 for ground truth annotation, data curation and data analysis. The final release of DFUC2021 consists of 15,683 DFU patches, with 5,955 training, 5,734 for testing and 3,994 unlabeled DFU patches. The ground truth labels are four classes, i.e. control, infection, ischaemia and both conditions. We curate the dataset using image hashing techniques and analyse the separability using UMAP projection. We benchmark the performance of five key backbones of deep learning, i.e. VGG16, ResNet101, InceptionV3, DenseNet121 and EfficientNet on DFUC2021. We report the optimised results of these key backbones with different strategies. Based on our observations, we conclude that EfficientNetB0 with data augmentation and transfer learning provided the best results for multi-class (4-class) classification with macro-average Precision, Recall and F1-score of 0.57, 0.62 and 0.55, respectively. In ischaemia and infection recognition, when trained on one-versus-all, EfficientNetB0 achieved comparable results with the state of the art. Finally, we interpret the results with statistical analysis and Grad-CAM visualisation.
