摘　　要：提出一种改进的CANDIDE三维人脸模型,并采用顶点规则化和NURBS曲面拟合方法获得光滑的模型表面,从而可以合成各种不同姿态和光照变化的人脸图像,为人脸识别方法的研究提供逼真的虚拟样本。In this paper, an improved CANDIDE model is proposed, and a smooth face surface model is obtained by using vertex regulation and NURBS curve surface fitting. Thereby various face images with different head poses and lighting conditions can be synthesized and these images can be used as virtual samples for face recognition.

关 键 词：CANDIDE模型 顶点规则化 曲面拟合
