| Outline of Final Research Achievements |
In this research, principal component analysis is applied to pigmentation distributions, surface reflectance components and facial landmarks in the whole facial images to obtain feature values. Furthermore, the relationship between the obtained feature vectors and age is estimated by multiple regression analysis to modulate facial images in woman of ages 10 to 70. In the beauty industry, the synthesis of skin texture is based on these two kinds of feature values. In our previous work, we analyzed only pigmentation distributions and the reproduced images looked younger than the reproduced age in many instances by the subjective evaluation. We considered that this happened because we did not modulate the facial structures and detailed surfaces such as wrinkles. By analyzing landmarks represented facial structures and surface reflectance components, we analyze the variation of facial structures and fine asperity distributions as well as pigmentation distributions in the whole face.
