Analysis of human perception of facial skin radiance by means of image histogram parameters of surface and subsurface reflections from the skin

Background

The appearance of the skin is the result of complicated light–skin interactions involving surface and subsurface reflections. Radiant skin is a complicated attribute but is important for skin beauty. The aim of the present study was to achieve an understanding of the association between human perceptions of skin radiance and image histogram parameters from technically recorded images of surface and subsurface reflections.



Methods

Facial images of 45 subjects were evaluated visually by 30 respondents and were also computer analyzed in terms of their image histogram parameters. A partial least squares regression model ...
