【摘要】：自然界的許多生物和物體都存在著一定的對稱性。這些對稱性包括旋轉對稱,鏡像對稱以及分形等。雖然絕對的對稱十分罕見,我們仍然可以對現實世界中的實物建模進行對稱性分析,探索和改進其自身的對稱性。其中,人臉就是一個典型的、滿足鏡像對稱的重要研究對象。近年來,隨著諸如微軟Kinect等商用深度攝像機的出現和相關領域的研究,我們可以經濟、高效地采集和構建大量的人臉模型,這使得對人臉模型進行對稱性分析顯得愈發(fā)重要。本文提出并實現了一套能夠魯棒地分析人臉對稱性的工具,從而能夠對人臉模型的對稱性進行逐點對的評分以及對稱性的修復。實驗表明,我們提出的方法相比于傳統(tǒng)的對稱性分析方法,可以在人臉模型上獲得更好的效果。
[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.
