This article presents a new numerical method for facial reconstruction. The problem is the following: given a dry skull, reconstruct a virtual face that would help in the identification of the subject. The approach combines classical features as the use of a skulls/faces database and more original aspects: (1) an original shape matching method is used to link the unknown skull to the database templates; (2) the final face is seen as an elastic 3D mask that is deformed and adapted onto the unknown skull. In this method, the skull is considered as a whole surface and not restricted to some anatomical landmarks, allowing a dense description of the skull/face relationship. Also, the approach is fully automated. Various results are presented to show its efficiency.
本文提出了一种用于面部重建的新数值方法。问题如下:给定一个干燥的颅骨,重建一个有助于识别该对象的虚拟面部。该方法结合了经典特征,如使用颅骨/面部数据库,以及更具创新性的方面:(1)使用一种原始的形状匹配方法将未知颅骨与数据库模板进行关联;(2)最终的面部被视为一个弹性3D面罩,该面罩会变形并适配到未知颅骨上。在这种方法中,颅骨被视为一个完整的表面,而不限于某些解剖标志点,从而能够对面骨/面部关系进行密集描述。此外,该方法是完全自动化的。给出了各种结果以展示其有效性。
