三维颅骨形态量化表示与非线性性别判定
Nonlinear sex determination and three dimensional quantitative representation of the skull morphology
摘要
Abstract
Sex identification based on 3D skull morphology has great significance and application value in forensic science and in facial reconstruction.Ninety four (94) skull samples from Shaanxi Province were used in the present study.Home-made software and knowledge of forensic science and anatomy were used to calibrate 62 salient feature points;Both non-measurable and measurable feature points were extracted,and the nonmeasurable characteristics of the skull were quantified.The combination of nonlinear dimension reduction and nonlinear classifier enabled sex determination.It was found that all fusion characteristic can obtain more gender discrimination information.The method of nonlinear dimension reduction and nonlinear classifier enhanced the accuracy and outperformed most of the state-of-the-art methods.关键词
