摘要:

尽管已经报道了用于黑素瘤的高度精确的自动化诊断技术,但是由于难以获得可靠的训练数据,实现能够基于医学指标提供诊断证据的系统仍然是一个悬而未决的问题。在本文中,我们提出了批量生产增强(BPA),以生成高质量,多样化的伪皮肤肿瘤图像与所需的结构恶性特征的额外的训练图像从有限数量的标记图像。提出的BPA作为一个有效的数据增强在构建特征检测器的非典型色素网络(APN),这是一个关键的结构在黑色素瘤诊断。实验表明,使用我们的BPA生成的图像进行训练,在接收器操作特征曲线下的区域中,APN检测性能大大提高了20.0个百分点,比传统的基于CycleGAN的AUC增强高出11.5到13.7个百分点。

英文摘要:

Although highly accurate automated diagnostic techniques for melanoma have been reported, the realization of a system capable of providing diagnostic evidence based on medical indices remains an open issue because of difficulties in obtaining reliable training data. In this paper, we propose bulk production augmentation (BPA) to generate high-quality, diverse pseudo-skin tumor images with the desired structural malignant features for additional training images from a limited number of labeled images. The proposed BPA acts as an effective data augmentation in constructing the feature detector for the atypical pigment network (APN), which is a key structure in melanoma diagnosis. Experiments show that training with images generated by our BPA largely boosts the APN detection performance by 20.0 percentage points in the area under the receiver operating characteristic curve, which is 11.5 to 13.7 points higher than that of conventional CycleGAN-based augmentations in AUC.
