Relationship Between Long-Term Variability of Facial Hue Information in Physiological and Psychological ROIs and Health Condition

In this study, we evaluate the relationship between long-term variability of facial hue information in physiological and psychological regions interests (ROIs) health condition. Long-term information, RGB, L*a*b* color space, were obtained from 13 ROIs visible images measured for approximately six months. evaluation was performed based on four conditions (absolute value absolute L*a*b*, relative L*a*b*). These variabilities applied to principal component analysis clarify The results suggested that chromaticity around periorbital region may be related conditions. Furthermore, states condition estimated with accuracy 80% using region.
