A method is described for synthesizing color images of whole human face with foundation make-up by using bare face image and the surface-spectral reflectance of the bare cheek. The synthesis of made-up facial images is based on the estimation of skin color with foundation make-up and the control of skin texture. First, the made-up skin color is estimated from the spectral reflectance of the bare cheek and the op- tical properties of the foundation. The spectral reflectance of made-up skin is calculated by the Kubelka-Munk theory. Second, smooth texture control is done by the intensity change of layers in the multi-resolution analysis with the Daubechies wavelet. Luster is enhanced and acnes are attenuated by the texture control. Experimental results show the accu- rate estimation of made-up skin color and the effective texture control. It is shown that the made-up face images are rendered with sufficient accuracy.

Especially, the synthesis of make-up skin color and texture are needed to examine the effect of make-up to human skin. Foundation is one of cosmetics to conceal undesirable color on skin and gives basic color and luster to the skin. It is important to evaluate the change of skin condition by the application of the foundation on the skin. In a previous paper [1], we proposed a method for estimating the skin color with foundation make-up. The main idea of the method was based on the fact that skin color with foundation make-up could be computed from the measured reflectance of the bare skin and the optical properties of the foundation by the Kubelka-Munk theory. The made-up skin color without texture was estimated for small areas of cheek. We also analyzed skin texture based on the multi-resolution analysis (MRA) using wavelet transform [2]. A. Tr´ emeau, R.
