Abstract
We propose a new method to predict the images
on a CRT and a hardcopy of skin color under
various illuminants. Spectral reflectance
of human skin is analyzed by principal component
analysis and it is shown that the spectral
reflectance can be estimated by three basis
functions. The estimation allows colorimetric
color reproduction without colorimetric measurements
for each illuminant. The proposed method
is verified by several skin color patches
taken by a calibrated HDTV camera. The method
is also applied to practical facial pattern
images.
