“…Studying the shape of the human head and face is a multidisciplinary field of study of great importance in medicine, archaeology and anthropology. In the medical field and biomedical research, accuracy and efficiency in the evaluation of craniofacial morphology play an important role in various disciplines, from the identification of syndromic craniofacial disorders [ 1 ] to forensic anthropology [ 2 , 3 ]. The search for tools and techniques that allow the precise acquisition of 3D morphometric data has become a recurring objective in the scientific community.…”

Obtaining 3D craniofacial morphometric data is essential in a variety of medical and educational disciplines. In this study, we explore smartphone-based photogrammetry with photos and video recordings as an effective tool to create accurate and accessible metrics from head 3D models. The research involves the acquisition of craniofacial 3D models on both volunteers and head mannequins using a Samsung Galaxy S22 smartphone. For the photogrammetric processing, Agisoft Metashape v 1.7 and PhotoMeDAS software v 1.7 were used. The Academia 50 white-light scanner was used as reference data (ground truth). A comparison of the obtained 3D meshes was conducted, yielding the following results: 0.22 ± 1.29 mm for photogrammetry with camera photos, 0.47 ± 1.43 mm for videogrammetry with video frames, and 0.39 ± 1.02 mm for PhotoMeDAS. Similarly, anatomical points were measured and linear measurements extracted, yielding the following results: 0.75 mm for photogrammetry, 1 mm for videogrammetry, and 1.25 mm for PhotoMeDAS, despite large differences found in data acquisition and processing time among the four approaches. This study suggests the possibility of integrating photogrammetry either with photos or with video frames and the use of PhotoMeDAS to obtain overall craniofacial 3D models with significant applications in the medical fields of neurosurgery and maxillofacial surgery.

The objective of the study was to determine the characteristics and perspectives of the use of computer simulation as a method for investigating crimes committed in the course of an armed conflict. In addition, the study involved a system approach, descriptive analysis, systematic sampling, doctrinal approach and prognostic methods. The author chooses the technological direction of application of the simulation (prospective or retrospective) and simulates the characteristics of the event, the identity of the offender, the victim of the crime and the sequence of the investigation process. In the course of hostilities, computer simulation can be performed by representatives of national and international law enforcement agencies, depending on the type of crime. Computer simulation in the course of armed conflict requires standardization of procedures and improvement of the substantive and instrumental components of the application of this method. It is concluded that this model has different perspectives for its development, which include: standardization of procedures with due regard to the specifics of the crime committed and the offender; details of information sources; technological direction of simulation; possible types of models; and, the need/appropriateness of involving international coordination assistance.
