Preliminary Study of Video Images of Humans in Portrait Examination

Abstract

The paper discusses the promising trends of a preliminary study of a person’s appearance captured using video recording devices. A characteristic of the preliminary study of the portrait data storage device seized during the inspection of the accident location is a sequential study of their external characteristics and internal content in order to further solve diagnostic problems aimed at establishing the characteristics of the surveying, image quality, and lack of signs of changing the initial content of the video or photo image. To date, the possibility of diagnosing human characteristics by age, physique, clothing, and manner of walking is being studied. According to the results of the analysis of scientific literature and practical activities of experts, it can be concluded that it is necessary to improve the methodology of portrait examination by including computer technologies for studying surveying parameters and signs of possible interference with the recording integrity. At the same time, to effectively identify the characteristics and states of people’s appearance transmitted by means of modern storage devices of portrait images, it is important that a team of experts conduct a comprehensive study of the images taking into account the knowledge in anatomy, anthropology, forensic medicine, computer technology, mathematical modeling, etc.
