基于照片的个性化人脸建模系统研究

An Image-Based Individual Facial Modeling Generation System

三维个性化人脸建模一直是计算机图形学中一个具有挑战性的课题。论文建立了一个基于照片的个性化人脸建模通用系统。根据MPEG-4确定出标准模型特征点的位置,从正面和侧面两幅照片出发,进行特征点编辑,获取人脸的关键特征点的位置,然后对标有对应特征点的标准模型进行变形,进行纹理映射,最后获得了真实的个性化人脸模型。该系统操作方便,可以快速地建立个性化人脸模型,为三维人脸动画提供了真实模型。

Modeling of hu ma n face is always a challenging task in computer graphics.In this paper,a metho d for im-age-based individual face modeling generation system is presented.Ac cording to MPEG-4,we affirm feature points on the general model,then edit f eature points on two perpendicular images,and obtain key feature points of hum an face,then deform the general model and go along texture mapping,at last get a realistic individual model.The experiment re-sults demonstrate that our a lgorithm is a simple,quick one,which provides a realistic model for human face animation.
