人体皮肤的自动检测已成为机器视觉系统的重要任务。之前关于这个主题的视觉和图形研究主要集中在传统彩色相机获取的图像上。正式的光谱分析主要在医学领域进行，重点是病理检测。我们建造了一个能够进行准确、密集和可重复的反射率测量的设施。在精确校准的照明条件下，使用高分辨率、高精度光谱仪测量从皮肤反射的光。本文介绍了在该设施收集的第一批数据的意见。从迄今为止收集的测量结果中，我们观察到了皮肤反射率的与人群无关的因素。我们将展示如何利用这些因素在皮肤识别。最后，我们提供了一个生物学的解释，在人类皮肤反射率的区别模式的存在。宾夕法尼亚大学计算机与信息科学系技术报告MSCIS-99-29。该技术报告可在ScholarlyCommons网站上获得：http://repository.upenn.edu/cis_reports/584人类皮肤的反射光谱技术报告MS-CIS-99-29 Elli Angelopoulou GRASP实验室计算机与信息科学系宾夕法尼亚大学elli@grip.cis.upenn.edu
The automated detection of human skin has become an important task for machine vision systems. Prior vision and graphics research on this topic has primarily focused on images acquired with conventional color cameras. Formal spectrographic analyses have largely been undertaken in the medical domain and focus on the detection of pathology. We have constructed a facility capable of producing accurate, dense and repeatable reflectance measurements. The light reflected from the skin is measured using a high resolution, high accuracy spectrograph under precisely calibrated lighting conditions. This paper presents observations from the first body of data gathered at this facility. From the measurements collected thus far, we have observed populationindependent factors of skin reflectance. We show how these factors can be exploited in skin recognition. Finally, we provide a biological explanation for the existence of a distinguishing pattern in human skin reflectance.
