人脸老化与逆龄技术在电影特效制作中的应用浅析

Analysis of the Application of Facial Aging and De-Aging Techniques in Film Special Effects Production

在银幕上实现角色人脸的老龄化和逆龄化一直是电影创作者面临的一个挑战,为了能真实地展现角色外观在年龄上的变化,许多制作团队都曾尝试过不同的方法。本文通过研究人脸老化与逆龄技术在电影特效制作中的应用发展,对从电影早期的特效化妆到使用替身或年轻演员代替出演,再到当下以动作捕捉技术为支撑的数字化人脸老化与逆龄技术的应用情况进行了梳理,并以影片《爱尔兰人》中逆龄角色的制作流程为例,展示了一种基于无标记点面部捕捉的软件系统Flux,并结合该技术的特征,对当今人工智能飞速发展背景下电影特效制作的应用发展进行探讨。

Achieving the facial ageing and de-ageing of a character on screen has always been a challenge for film creators,and many production teams have experimented with different approaches in order to realistically represent the age-related changes in a character's appearance.This paper examines the development of facial ageing and de-ageing technology in film special effects production,from the early stage of special effects make-up to the use of stand-ins or young actors instead,to the current application of digital facial ageing and de-ageing technology supported by motion capture technology.The article takes the production process of the de-ageing character in The Irishman as an example,demonstrates a software system based on facial capture without markers,known as Flux,and discusses the application of this technology in the context of the rapid development of artificial intelligence in film special effects production nowadays.
