【摘要】：自然界的许多生物和物体都存在着一定的对称性。这些对称性包括旋转对称,镜像对称以及分形等。虽然绝对的对称十分罕见,我们仍然可以对现实世界中的实物建模进行对称性分析,探索和改进其自身的对称性。其中,人脸就是一个典型的、满足镜像对称的重要研究对象。近年来,随着诸如微软Kinect等商用深度摄像机的出现和相关领域的研究,我们可以经济、高效地采集和构建大量的人脸模型,这使得对人脸模型进行对称性分析显得愈发重要。本文提出并实现了一套能够鲁棒地分析人脸对称性的工具,从而能够对人脸模型的对称性进行逐点对的评分以及对称性的修复。实验表明,我们提出的方法相比于传统的对称性分析方法,可以在人脸模型上获得更好的效果。
[Abstract]:There are some symmetries in many living things and objects in nature. These symmetries include rotational symmetry, mirror symmetry, fractal and so on. Although absolute symmetry is rare, we can analyze the symmetry of physical modeling in the real world and explore and improve its own symmetry. Among them, the face is a typical, satisfying mirror symmetry important research object. In recent years, with the appearance of commercial depth cameras such as Microsoft Kinect and the research in related fields, we can collect and construct a large number of face models economically and efficiently, which makes symmetry analysis of face models become more and more important. In this paper, we propose and implement a set of tools to analyze the symmetry of human face robustly, so that the symmetry of the face model can be evaluated point by point and the symmetry can be repaired. Experiments show that compared with the traditional symmetry analysis method, the proposed method can achieve better results on the face model.
