A STUDY OF THE MODERN JAPANESE FACE SHAPE USING FUZZY THEORY

Abstract

A fuzzy theory is applied to thinking the facial differences between the two racial group-types, the Jomon (more than 2000 years ago, RI=1.000) and the Kofun (about 1500 years ago, RI=2.000). Many modern Kumamoto men show the racial index (RI) of the Kofun type as well as the modern Kanto men and Tokugawa Ienobu. The Yayoi men show the middle value, but RI of the Medieval men is close to that of the Kofun. One of the Kumamoto Yayoi men and two modern Kumamoto men are very close to the Jomon type.
