摹拟画像技术作为一种侦查手段已被广泛应用。在1000多年前,古人已运用画像的方法缉拿罪犯。由于摹拟画像需要手工制作,因而这项技术发展非常缓慢。直到20世纪60年代出现合成方法制作摹拟画像,才使这项技术在刑事侦查工作中得到普遍应用。近年来,随着计算机图像技术的应用,形成了计算机摹拟画像技术,从而使更多的人可以掌握使用,使这项技术得到了普及。正确地运用摹拟画像技术,可以为侦查工作提供重要线索,在侦查破案中发挥重要作用。寻找目击证人寻找目击证人是制作摹拟画像的必要条件,这项工作在任何案件侦查中都是非常重要的。原则上说,进行摹拟画像的条件是普遍存在的。案犯在实施犯罪的过程中,必然与周围的人有过接触。我们所以有时找不到目击证人,只能说明案犯正在实施犯罪的过程可能没有人看到,然而这并不表明其在实施犯罪前或实施犯罪后都没有人看到,只是在一些情况下由于条件
As a means of investigation, imitative portrait has been widely used. More than 1,000 years ago, the ancients used portraits to capture criminals. This technique has been slow to develop due to the need for hand-made mimicry. It was not until the 1960s that synthesis methods were used to produce imitative portraits that made this technique universally applied in criminal investigations. In recent years, with the application of computer image technology, computer simulation portrait technology has been formed, so that more people can grasp the use of this technology has been popularized. Proper use of imitative portrait technology can provide important clues for investigation work and play an important role in investigation and case detection. Finding eyewitnesses Finding witnesses is a sine qua non for making mimicry, a work that is very important in any case investigation. In principle, the conditions under which the portrait is mimicked are ubiquitous. In the process of committing a crime, the criminal must have had contact with the people around him. Sometimes, we can not find any witnesses. It only shows that no one can see that the criminal is actually committing a crime. However, this does not mean that he or she has not seen anyone before or after committing an offense. In some cases, condition
