论文摘要
背景：探索如何通过使用常规智能手机拍摄的消费者级图像来改善产品试验对皮肤化妆品的功效。 材料和方法：30至60岁的12名妇女参加了一项产品试验，并在4周的开始和结束时使用了高分辨率Antera 3D CS摄像头拍摄的脸颊和寺庙区域的特写图像。此外，在整个试验期间，他们每个人都有``自拍照''的脸。自动图像分析以识别肤色的变化使用了三种颜色归一化和皱纹组成的分析确定边缘并计算了它们的幅度。 结果：试验开始和结束时拍摄的图像是智能手机图像归一化的基线地面真相，并在试验期间对许多志愿者显示出颜色和皱纹幅度的巨大变化。结论：结果表明，在试用期内定期使用自拍智能手机图像可以增加对试验功效的解释的价值。
Background: To explore how the efficacy of product trials for skin cosmetics can be improved through the use of consumer-level images taken by volunteers using a conventional smartphone. Materials and Methods: 12 women aged 30 to 60 years participated in a product trial and had close-up images of the cheek and temple regions of their faces taken with a high-resolution Antera 3D CS camera at the start and end of a 4-week period. Additionally, they each had ``selfies'' of the same regions of their faces taken regularly throughout the trial period. Automatic image analysis to identify changes in skin colour used three kinds of colour normalisation and analysis for wrinkle composition identified edges and calculated their magnitude. Results: Images taken at the start and end of the trial acted as baseline ground truth for normalisation of smartphone images and showed large changes in both colour and wrinkle magnitude during the trial for many volunteers. Conclusions: Results demonstrate that regular use of selfie smartphone images within trial periods can add value to interpretation of the efficacy of the trial.
