基于一般人脸模型修改的特定人脸合成技术

目前计算机模拟领域中的人脸合成技术由于其广泛的应用前景得到了越来越多的重视，它可以用于人们语言感知模型研究、虚拟环境、通信技术、辅助教学、医疗研究、电影制作、游戏娱乐等诸多方面。由于在实现中人脸的千差万别，使一般人脸模型的个体化成为人脸合成中的一项关键技术。个体人脸的差异主要表现在不同的面部几何特征和纹理特征两方面。针对这两方面，在已知一般人脸中性模型与一般人脸基本表情模型基础上，根据特定人脸不同

SPECIFIC FACE SYNTHESIS BASED ON THE MODIFICATION OF THE GENERAL FACE MODEL

Much attention has been placed on the human face synthesis techniques in the field of computer animation because of the wide use foreground.It can be used in the human language perception model investigation, virtual environment, telecommunication technique, education, medicine, film, game and entertainment etc. As a result of the differences among faces in the reality, general human face model individuality becomes a key technique of human face synthesis. The determinant differences among faces are geometrical features and texture features. According to the facial geometrical features of a specific person, global and local transformation is applied to accomplish the modification from neutral general face model to neutral specific face model. After this, vector space displacement transformation is designed to generate the basic expression of specific face model based on the hypothesis that both the neutral and the basic expressions of general facial model had already been known.At last,multi direction texture mapping technique is presented in this paper to enhance the realistic synthesized results of the specific human face.
