科学领域:

  • 医学美学 医学美学
  • 皮肤病学中的人工智能
  • 计算机视觉用于临床分析.

背景情况:

  • 鼻皮 (NLF) 的严重程度是面部衰老的关键标志物,也是美学干预的共同焦点.
  • 纹严重性评级表 (WSRS) 是对NLF严重性进行分级的标准临床工具,但受到主观性和观察者之间的变化影响.

研究的目的:

  • 开发和验证DeepFold,这是一个基于WSRS的深度学习组合模型,用于基于WSRS的NLF严重程度的自动化,客观和可解释的分级.
  • 建立可靠的人工智能驱动的方法来评估NLF严重程度,克服当前主观尺度的局限性.

主要方法:

  • 三名整形外科医生使用WSRS策划和注释了6,718张面部图像的数据集.
  • 采用了ResNet-50架构,使用三个独立训练的网络中的多数投票组合策略.
  • 模型训练利用焦点损失来解决类失衡和早期停止,通过准确性,F1得分和混矩阵分析来评估性能.

主要成果:

  • 深层组合模型实现了0.917的验证准确度和0.917的F1得分.
  • DeepFold的表现优于个别基线模型,包括ResNet-50 (精度:0.904) 和SeResNet-50 (精度:0.882).
  • 合并方法显示预测差异减少,稳定性提高,特别是在阶级不平衡的情况下.

结论:

  • DeepFold提供了一种可靠和标准化的方法来评估NLF的严重程度.
  • 该模型具有重要的潜在临床价值,用于审美评估,治疗规划和治疗结果监测.
  • 使用DeepFold的自动NLF分级可以提高临床实践中的客观性和一致性.
