Survey on Craniofacial Reconstruction Method

Craniofacial reconstruction studies the restoration of facial features according to the corresponding human skulls.It is widely used in many fields such as public security forensics,archaeology,medical plastic surgery etc.There are mainly two kinds of craniofacial reconstruction,the traditional craniofacial reconstruction and computer-assisted craniofacial reconstruction.The traditional manual craniofacial reconstruction is time-consuming and the results are often hard to achieve.In contrast,the computer-assisted craniofacial reconstruction is more realistic and efficient.This study focuses on the summarization and analysis of computer-assisted craniofacial reconstruction technologies,including knowledge-based craniofacial reconstruction method and statistical model method.We present elaborate introductions to some important methods,such as the craniofacial reconstruction method based on sparse soft tissue thickness,the craniofacial reconstruction method based on the thickness of dense soft tissue,the statistical deformation model method and the regression model method.The advantages and disadvantages of these methods are compared to help researchers get a comprehensive understanding on craniofacial reconstruction.
