Melanoma is a fatal form of skin cancer when left undiagnosed. Computer-aided diagnosis systems powered by convolutional neural networks (CNNs) can improve diagnostic accuracy and save lives. CNNs have been successfully used in both skin lesion segmentation and classification. For reasons heretofore unclear, previous works have found image segmentation to be, conflictingly, both detrimental and beneficial to skin lesion classification. We investigate the effect of expanding the segmentation border to include pixels surrounding the target lesion. Ostensibly, segmenting a target skin lesion will remove inessential information, non-lesion skin, and artifacts to aid in classification. Our results indicate that segmentation border enlargement produces, to a certain degree, better results across all metrics of interest when using a convolutional based classifier built using the transfer learning paradigm. Consequently, preprocessing methods which produce borders larger than the actual lesion can potentially improve classifier performance, more than both perfect segmentation, using dermatologist created ground truth masks, and no segmentation altogether.
当未被诊断时,黑色素瘤是一种致命形式的皮肤癌。由卷积神经网络 (CNN) 驱动的计算机辅助诊断系统可以提高诊断准确性并拯救生命。CNN 已成功用于皮肤病变分割和分类。由于迄今为止尚不清楚的原因,以前的工作发现图像分割对皮肤病变分类既有不利影响,也有有利影响。我们研究了扩大分割边界以包含目标病变周围像素的效果。表面上,分割目标皮肤病变将去除不必要的信息、非病变皮肤和伪影,以帮助分类。我们的结果表明,当使用基于卷积的分类器时,使用迁移学习范例构建,扩大分割边界会在所有感兴趣的指标上产生一定程度的更好结果。因此,产生大于实际病变边界的预处理方法有可能比使用皮肤科医生创建的地面真实掩模进行完美分割和完全不分割都能提高分类器性能。
