背景/目的：最近关于面部皮肤随年龄变化的研究主要利用一阶和二阶统计量分析了它们与图像和色度特性变化的相关性。这项研究的目的是揭示三阶统计量的重要性，并将这些图像特性与皮肤年龄感知联系起来。方法：在受控环境中拍摄了118名年龄从13岁到80岁的日本女性的面部照片。随后，10名日本受试者从原始面部图像的脸颊区域对皮肤斑块的年龄感知进行了评分。结果：皮肤斑块的年龄估计与其实际年龄高度相关，证明我们的皮肤斑块包含了足够的年龄估计信息。此外，感知年龄与颜色和亮度的统计值显著相关。在CIELAB1976中，年龄知觉与所有通道的三阶统计量显著相关。结论：我们的结果揭示了高阶统计量在皮肤非侵入性皮肤质量评估中的重要性。
Background/purpose: Recent research on the age-dependent changes of facial skin has analyzed their correlation with changes in image and colorimetric properties using mainly first- and second-order statistics. The aim of this study is to reveal the importance of third-order statistics and relate those image properties to skin age perception.Methods: Photographs of the faces of 118 Japanese women ranging in age from 13 to 80 years were taken in a controlled environment. Subsequently, 10 Japanese subjects rated the age perception of skin patches from the cheek area of the original facial images.Results: The age estimation of the skin patches was highly correlated with its chronological age proving that our skin patches contain enough information for age estimation. Also, the perceived age was significantly high correlated to color and lightness statistical values. Specifically, age perception was significantly high correlated with third-order statistics of all channels in CIELAB1976.Conclusion: Our results reveal the importance of higher order statistics for the development of nonintrusive skin quality assessments of the skin.
