Abstract

Age progression technique involves a reworking of the photo of a missing person in accordance with the guidelines drawn up by medical sciences on aging. Here we present the age progression of photos of individuals who are not missing persons, so the photos of their current appearance are available. The creation of age progressions in blind starting from photos of them as children made it possible to evaluate the effectiveness of the technique.

The age progression was carried out based on a photo of Individual A and Individual B. First, the study of the facial features defined the morphology according to the standard classification, then reference images characterized by morphologies consistent with those of the original image were searched for. Thanks to Adobe Photoshop 2023 software, the creation of a collage was made. Finally, the result was compared with the current photo of the individual.

The analysis of the two age progressions carried out gave different results. In the age progression of Individual A, the morphology of the facial features reveals similarities with slight errors in the comparison with his photo at 19 years old. Regarding the age progression of Individual B’s face, doubts were raised regarding both skin tone and haircut.

The positive and negative aspects found in these age progressions are of great importance in evaluating the accuracy of the results. Thanks to continuous practice, the age progression technique can be improved so that it can be a real support tool for the search for long-time missing persons.

年龄递进技术：研究与效果评价

年龄递进技术涉及根据医学科学关于衰老的指导方针对失踪者的照片进行重新加工。在这里，我们呈现了非失踪人口的个人照片的年龄变化，因此他们目前的外表照片是可用的。从盲人儿童时期的照片开始，创建他们的年龄进展，使评估该技术的有效性成为可能。基于个体a和个体b的一张照片进行年龄递进，首先对面部特征进行研究，根据标准分类定义形态学，然后搜索形态学特征与原始图像一致的参考图像。多亏了Adobe Photoshop 2023软件，拼贴画的创作完成了。最后，将结果与个人的当前照片进行比较。对两种年龄进展的分析得出了不同的结果。在A个体的年龄发展过程中，面部五官的形态与他19岁时的照片比较有相似之处，但有轻微的误差。对于个人B脸部的年龄变化，肤色和发型都有疑问。在这些年龄进展中发现的积极和消极方面对于评估结果的准确性非常重要。由于不断的实践，年龄递进法可以得到改进，从而成为寻找长期失踪人员的真正辅助工具。
