Article Synopsis
- Cranial sex estimation traditionally relies on visual assessments by forensic anthropologists, which can be biased and less accurate for diverse populations.
- This study investigates a deep learning (DL) framework to improve sex estimation accuracy using 200 CT scans of Indonesian individuals, finding that the top DL model achieved 97% accuracy, significantly higher than the human observer's 82%.
- The results suggest that DL models can effectively analyze cranial traits while considering overall size and shape, offering a valuable tool to enhance the reliability of sex estimation in forensic anthropology.
Unlabelled: Forensic anthropology and forensic facial image identification are areas with two aspects in common: (i) the use of anthropological knowledge concerning human variation in their analyses and (ii) low numbers of accredited forensic units. While the low numbers are often explained by the uniqueness of human identification cases, given the high level of scrutiny in the forensic sciences, interest in and efforts to achieve accreditation have become increasingly prominent. Therefore, this study aimed to obtain accreditation-relevant information about the working environment in facial image comparison units by surveying facial examiners across Europe.

- Research investigates whether non-professional facial photographs can effectively be used for facial analysis, contrasting with the established use of professional photos.
- The study involved measuring the facial profiles of 74 young adults using direct anthropometry, alongside taking both professional and non-professional photographs for comparison.
- Findings suggest that many facial features, particularly vertical dimensions and eye measurements, can be reliably analyzed using non-professional photos without significant differences compared to professional ones.
Article Synopsis
- 3D structured light scanning is a useful tool in forensic anthropology for creating accurate models of skeletal remains, which aids in analysis, data sharing, and legal presentations without risking damage to originals.
- The study evaluates the accuracy of 3D scans and prints for ten different bone types by comparing standard measurements from physical bones, virtual models, and printed versions, using specific statistical methods to quantify errors.
- Results show that measurements from virtual models and prints are generally accurate (within ±2 mm), but some bones were less reliable for specific measurements; overall, the technique meets acceptable standards for forensic analysis.
