摘要:

最近的猴痘疫情由于在非洲以外的40多个国家迅速蔓延,已成为一个公共卫生问题。猴痘的早期临床诊断具有挑战性,因为它与水痘和麻疹相似。在不容易得到确证性聚合酶链反应检测的情况下,计算机辅助检测猴痘病变可能有利于监测和迅速查明疑似病例。已经发现深度学习方法在皮肤病变的自动检测中是有效的,只要有足够的训练样本可用。然而,到目前为止,这样的数据集还不能用于猴痘疾病。在目前的研究中,我们首先开发了“猴痘皮肤病变数据集(MSLD)”,包括猴痘,水痘和麻疹的皮肤病变图像。这些图像主要来自网站、新闻门户网站和可公开访问的病例报告。采用数据增强的方法增加样本量,并进行了3倍交叉验证实验。在下一步中,使用几个预训练的深度学习模型,即VGG-16,ResNet 50和InceptionV 3来分类猴痘和其他疾病。还开发了三种模型的集成。ResNet 50实现了$82.96(\pm4.57\%)$的最佳总体精度,而VGG 16和集成系统分别实现了$81.48(\pm6.87\%)$和$79.26(\pm1.05\%)$的精度。还开发了一个原型网络应用程序,作为在线猴痘筛查工具。虽然在这个有限的数据集上的初步结果是有希望的,但需要更大的人口统计学上多样化的数据集,以进一步提高这些模型的普遍性。

英文摘要:

The recent monkeypox outbreak has become a public health concern due to its rapid spread in more than 40 countries outside Africa. Clinical diagnosis of monkeypox in an early stage is challenging due to its similarity with chickenpox and measles. In cases where the confirmatory Polymerase Chain Reaction (PCR) tests are not readily available, computer-assisted detection of monkeypox lesions could be beneficial for surveillance and rapid identification of suspected cases. Deep learning methods have been found effective in the automated detection of skin lesions, provided that sufficient training examples are available. However, as of now, such datasets are not available for the monkeypox disease. In the current study, we first develop the ``Monkeypox Skin Lesion Dataset (MSLD)" consisting skin lesion images of monkeypox, chickenpox, and measles. The images are mainly collected from websites, news portals, and publicly accessible case reports. Data augmentation is used to increase the sample size, and a 3-fold cross-validation experiment is set up. In the next step, several pre-trained deep learning models, namely, VGG-16, ResNet50, and InceptionV3 are employed to classify monkeypox and other diseases. An ensemble of the three models is also developed. ResNet50 achieves the best overall accuracy of $82.96(\pm4.57\%)$, while VGG16 and the ensemble system achieved accuracies of $81.48(\pm6.87\%)$ and $79.26(\pm1.05\%)$, respectively. A prototype web-application is also developed as an online monkeypox screening tool. While the initial results on this limited dataset are promising, a larger demographically diverse dataset is required to further enhance the generalizability of these models.
