摘要:

早期发现皮肤癌,特别是黑色素瘤,对于实现先进的治疗至关重要。由于皮肤癌数量的快速增长,对皮肤病变的计算机化分析的需求日益增长。用于皮肤病变的最先进的公共可用数据集通常伴随有非常有限的分割基础事实标记,因为它是费力且昂贵的。在皮肤镜图像中,病灶边界的分割对于病灶的准确定位和不同类型皮肤病灶的诊断至关重要。在这项工作中,我们提出使用全自动深度学习集成方法来精确分割皮肤镜图像中的病变边界。我们在ISIC-2017分割训练集上训练了Mask-RCNN和DeepLabv 3+方法,并在ISIC-2017测试集上评估了集成网络的性能。我们的研究结果表明,最好的集成方法分割皮肤病变的Jaccard指数为79.58%的ISIC-2017测试集。该集成方法在Jaccard指数上分别优于FrCN、FCN、U-Net和SegNet 2.48%、7.42%、17.95%和9.96%。此外,在ISIC-2017测试集上,所提出的集成方法对一些具有代表性的临床良性病例的准确率为95.6%,对黑色素瘤病例的准确率为90.78%,对脂溢性角化病病例的准确率为91.29%,表现出比FrCN,FCN,U-Net和SegNet更好的性能。

英文摘要:

Early detection of skin cancer, particularly melanoma, is crucial to enable advanced treatment. Due to the rapid growth in the numbers of skin cancers, there is a growing need of computerized analysis for skin lesions. The state-of-the-art public available datasets for skin lesions are often accompanied with very limited amount of segmentation ground truth labeling as it is laborious and expensive. The lesion boundary segmentation is vital to locate the lesion accurately in dermoscopic images and lesion diagnosis of different skin lesion types. In this work, we propose the use of fully automated deep learning ensemble methods for accurate lesion boundary segmentation in dermoscopic images. We trained the Mask-RCNN and DeepLabv3+ methods on ISIC-2017 segmentation training set and evaluate the performance of the ensemble networks on ISIC-2017 testing set. Our results showed that the best proposed ensemble method segmented the skin lesions with Jaccard index of 79.58% for the ISIC-2017 testing set. The proposed ensemble method outperformed FrCN, FCN, U-Net, and SegNet in Jaccard Index by 2.48%, 7.42%, 17.95%, and 9.96% respectively. Furthermore, the proposed ensemble method achieved an accuracy of 95.6% for some representative clinically benign cases, 90.78% for the melanoma cases, and 91.29% for the seborrheic keratosis cases on ISIC-2017 testing set, exhibiting better performance than FrCN, FCN, U-Net, and SegNet.
