随着计算机技术的普及,摹拟画像已由过去手工画像发展到电脑人像组合阶段。计算机摹拟画像的核心问题就是制作者与目击者之间有效的合作。这是决定摹拟画像是否成功的关键。目击者在摹拟画像中的作用有现场目击者是进行摹拟画像的前提条件。摹拟画像的第一手资料就是目击者的记忆。目击:目击者所处的环境、条件及心理状态直接影响目击者的观察效果。如观察的角度不同,所看到目击对象的相貌就会有所差异。正面观察和有一定角度观察到的脸型就会有差别,后者观察到的脸型比前者观察到的脸型要瘦一些或长一
With the popularization of computer technology, imitation portraits have been developed from hand-painted portraits to computer portraits. The central issue in computer simulations is the effective cooperation between producer and eyewitness. This is the key to determining the success of the mimicry. Witnesses’ role in mimicking portraits An on-site witness is a prerequisite for mimicking portraits. The first-hand information on the mimicry is the witness’s memory. Witness: Witnesses in the environment, conditions and mental state directly affect the witness’s observation effect. If you look at the different perspectives, you will see the look of the sighting object will be different. There is a difference between the positive observation and the face observed at a certain angle. The latter is observed to be thinner or longer than the one observed by the former
