Abstract

A method is presented to obtain realistic modifications of faces represented as sequences of tomograms, to be used for geometrical modelling or for planning of plastic surgery. This method uses a mathematical model consisting of the harmonic expansion of tomograms whose harmonic parameters are represented by cubic spline functions of the z variable. Based on this model a three dimensional shape editor is proposed that allows for local modifications. The results obtained using tomograms of a plaster mould are presented.

摘要

本文提出了一种方法，用于获取以断层图像序列表示的面部的逼真修改，以用于几何建模或整形手术规划。该方法使用一个数学模型，该模型由断层图像的谐波展开组成，其谐波参数由z变量的三次样条函数表示。基于此模型，提出了一种允许局部修改的三维形状编辑器。展示了使用石膏模型的断层图像获得的结果。
