生成学习是表征学习的一个强大工具,在生物医学成像问题上表现出了特别的希望。然而,在这种情况下,从分布中采样是次要的,以找到真实图像的表示,这往往带有标签,并明确表示目标分布的内容和质量。从生成模型忠实地重建图像仍然很困难,特别是那些像组织学图像一样复杂的模型。在这项工作中,结合了两种现有的方法(自动编码器和对抗性潜伏自动编码器),试图提高我们对非黑色素瘤皮肤癌,特别是表皮内癌(IEC)的真实图像进行编码和解码的能力。利用IEC(256 x 256)的高质量图像数据集,这项工作评估了图像重建质量和表示学习的结果。研究表明,对抗性训练可以将基线FID分数从76提高到50,并且表征学习的基准可以提高3%。平滑和现实的插值的形态结构的变化也首次提出,定位表示学习作为一个有前途的方向,在计算病理学的背景下。
英文摘要:
Generative learning is a powerful tool for representation learning, and shows particular promise for problems in biomedical imaging. However, in this context, sampling from the distribution is secondary to finding representations of real images, which often come with labels and explicitly represent the content and quality of the target distribution. It remains difficult to faithfully reconstruct images from generative models, particularly those as complex as histological images. In this work, two existing methods (autoencoders and adversarial latent autoencoders) are combined in attempt to improve our ability to encode and decode real images of non-melanoma skin cancer, specifically intra-epidermal carcinoma (IEC). Utilising a dataset of high-quality images of IEC (256 x 256), this work assesses the result of both image reconstruction quality and representation learning. It is shown that adversarial training can improve baseline FID scores from 76 to 50, and that benchmarks on representation learning can be improved by up to 3%. Smooth and realistic interpolations of the variation in the morphological structure are also presented for the first time, positioning representation learning as a promising direction in the context of computational pathology.
The Fast and Accurate Approach to Detection and Segmentation of Melanoma Skin Cancer using Fine-tuned Yolov3 and SegNet Based on Deep Transfer Learning
黑色素瘤是最严重的皮肤癌之一,可以发生在人类皮肤的任何部分。黑色素瘤病变的早期诊断将大大增加其治愈的机会。改善黑色素瘤分割将有助于医生或手术机器人更准确地从身体部位切除病变。近年来,基于学习的图像分割方法在图像分割中取得了较好的效果。这项研究提出了一种新的方法,通过定义一个基于深度学习模型的两步管道来改善黑色素瘤皮肤病变的检测和分割。我们的方法在ISIC 2018(皮肤病变分析对黑色素瘤检测挑战数据集)众所周知的数据集上进行了评估。所提出的方法包括两个主要部分的实时检测病变的位置和分割。在检测部分,皮肤病变的位置由微调的You Only Look Once第3版(F-YOLOv 3)精确检测,然后输入微调的分割网络(F-SegNet)。皮肤病变定位有助于减少用于分割的整个图像的不必要的计算。结果表明,我们提出的F-YOLOv 3在平均精度(mAP)方面表现更好,达到96%。与最先进的分割方法相比,我们的F-SegNet实现了更高的性能,准确率为95.16%。
