Forensic facial comparison (FFC) is a scientific technique used to link suspects to a crime scene based on the analysis of photos or video recordings from that scene. While basic guidelines on practice and training are provided by the Facial Identification Scientific Working Group, details of how these are applied across the world are scarce. FFC is frequently used in South Africa, with more than 700 comparisons conducted in the last two years alone. In this paper the standards of practice are outlined, with new proposed levels of agreement/conclusions. We outline three levels of training that were established, with training in facial anatomy, terminology, principles of image comparison, image science, facial recognition and computer skills being aimed at developing general competency. Training in generating court charts and understanding court case proceedings are being specifically developed for the South African context. Various shortcomings still exist, specifically with regard to knowledge of the reliability of the technique. These need to be addressed in future research.
法医面部比对（FFC）是一种科学技术，用于根据对犯罪现场照片或录像的分析，将嫌疑人与犯罪现场联系起来。虽然面部识别科学工作组提供了实践和培训的基本指南，但关于这些指南在全球范围内如何应用的细节却很少。FFC在南非经常被使用，仅在过去两年就进行了700多次比对。本文概述了实践标准，并提出了新的一致程度/结论水平。我们概述了已确立的三个培训级别，针对面部解剖学、术语、图像比对原理、图像科学、面部识别和计算机技能的培训旨在培养一般能力。针对南非的情况，正在专门开展生成法庭图表和理解法庭案件程序的培训。仍然存在各种缺点，特别是在该技术可靠性的知识方面。这些需要在未来的研究中加以解决。
