Abstract

A wavelet analysis based multi-resolution representation method is adopted to establish mathematical description of three-dimensional anthropometric head data in this paper. This method provides flexible description of shapes at different resolution levels. Three-dimensional anthropometric data analysis can then be performed with coarse resolutions, which preserve the major shape components but ignore micro shape components. In a case study of 510 3D head scans, quantitative approximation errors, which reflect the approximation of the low-resolution surface to the original one, have been investigated and demonstrated with respect to various decomposition levels.
