面向移动设备的快速人脸纹理映射

An Efficient Method of Face Texture Mapping Directed to Portable Devices

  • 摘要: 提出一种面向未来掌上移动设备(如高端手机,PDA等)的灵活实用的纹理映射方法.该方法仅需要一张正面人脸照片作为输入,不要求模型和纹理的精确匹配,通过简单的交互实现在较低资源配置下人脸纹理的提取.采用了一种交互调整映射的方案,通过用户对模型中特征点及其影响区域的编辑,实现对局部纹理坐标的定义,得到满意的映射效果.实验结果表明,文中方法具有较高的效率和真实感,可以用于产生真实感三维人脸表情动画.

     

    Abstract: In this paper, we proposed a novel flexible method to meet the future requirement of palm equipment application such as high performance mobile phone, PDA, etc. Based on a single frontal face image, at a lower resource configuration, the face texture is extracted through few interactions without the exact matching between model and texture. An interactive scheme is introduced to obtain the local texture coordinates through the user's editing and adjustment on the feature points and influencing area. Experimental result shows that our method is more efficient in generating a 3D realistic face, and it can be used to produce realistic 3D facial animation.
