Forensic facial approximation involves building a likeness of the head and face on the skull of an unidentified individual, with the aim that public broadcast of the likeness will trigger recognition in those who knew the person in life. This paper presents an overview of the collaborative practice between Ronn Taylor (Forensic Sculptor to the Victorian Institute of Forensic Medicine) and Detective Sergeant Adrian Paterson (Victoria Police Criminal Identification Squad). This collaboration involves clay modelling to determine an approximation of the person's head shape and feature location, with surface texture and more speculative elements being rendered digitally onto an image of the model. The advantages of this approach are that through clay modelling anatomical contouring is present, digital enhancement resolves some of the problems of visual perception of a representation, such as edge and shape determination, and the approximation can be easily modified as and when new information is received.
法医面部复原是指在身份不明者的颅骨上塑造出头部和面部的 likeness，目的是通过公开 likeness 来促使那些生前认识此人的人进行辨认。本文概述了罗恩·泰勒（维多利亚法医研究所法医雕塑家）与警探阿德里安·帕特森（维多利亚警方刑事识别小组）之间的合作实践。这种合作包括用黏土建模来确定人头形状和特征位置的近似值，然后将表面纹理和更多推测性元素以数字方式呈现到模型图像上。这种方法的优点在于，通过黏土建模可以呈现解剖轮廓，数字增强解决了图像视觉感知方面的一些问题，如边缘和形状确定，而且当收到新信息时，可以轻松修改近似值。
