In quantitative evaluation of facial skin chromophore content using color imaging, several factors such as view angle and facial influence of view angle and facial curvature on the accuracy of quantitative image analysis, we acquire cross-polarized diffuse reflectance color images of a white-patched mannequin head model and human subsurface skin color information and a head-positioning device that enabled acquisition of facial images in a reproducible fashion at a fixed distance from the illumination source.12 To investigate the influence of view angle on the uniformity of incident light distribution, the 99% diffuse reflectance standard placed in the head-positioning device and cross-polarized diffuse reflectance images were obtained at multiple view angles Three consecutive cross-polarized diffuse reflectance color images were acquired at the optimal view angle Cross-polarized diffuse reflectance images were acquired at the optimal view angle of 35 deg. ./cache/work_wtrnpcmm4zafdn6phpmyec3ewa.pdf ./txt/work_wtrnpcmm4zafdn6phpmyec3ewa.txt
