“…Rather, this study supports the concept that each situation is unique and should be treated as such. 14,15 However, there are drawbacks, such as the restricted number of visible teeth in the photograph, low image quality, the regressive alteration of teeth after the antemortem image was taken, and the difficulty of making comparisons due to the different orientation of the photo. 3 When in doubt, multiple parameters should be adopted to avoid bias and error.…”

Human identification may be difficult when there is no antemortem data available. A photograph of the deceased may be valuable in such cases. Digital advancement and inclusion in the lives of ordinary people makes it easier to retrieve clear, high-resolution photos from social media accounts and other places. This paper describes three cases of forensic dental identification from a US–Bangla plane crash in Nepal in which a charred body was positively identified from a smiling photograph provided by the deceased's family. Each case is unique and their identification rests on the availability of pre- and post-mortem information. Thus, the number of concordant points may vary from single to multiple; there is no defined criteria for minimum number of concordance for a positive dental identification.

“…Focal length is measured in millimeters (mm). Focal length is a lens parameter on the camera that shows the image object [46]. Focal length is the distance between the optical center and the camera sensor, which is used to adjust the focus of the image captured by the camera [47].…”

Camera is the main tool for monitoring shrimp underwater with a noninvasive method. Distance of the shrimp underwater with the varying camera causes the monitoring of the estimated shrimp size to be less accurate. This study provides a new solution to detect the distance of shrimp underwater with a camera using the Euclidian distance and triangle similarity algorithm. The problem raised in this study is how to measure the distance of a shrimp underwater with a camera. The method used has several stages, including using the grayscale image method, image thresholding, edge detection, detection of Region of Interest (ROI), determining the position of shrimp coordinates, calculating the length of shrimp coordinates, camera calibration using the triangle similarity algorithm, calculating the estimated distance of shrimp with the camera. The study results obtained a focal length value of 1298.58, the value of the distance between the shrimp and the camera (D') for 5 positions of shrimp underwater from 50 cm – 19.86 cm, and the RE value from 0% - 0.13%. In conclusion, this method can be used to measure the estimated distance between of moving shrimp and a camera with a low error rate.

A violent structure. Southern perspective on the practice of forensic anthropology as a public service

Global South perspective rarely reaches the academic vanguard. While they represent over 80% of the world population, the voices from less developed regions often are ignored in academic debate. This fact produces an important disequilibrium in relation to the dissemination of knowledge, sharing of experiences and exchange of thoughts and, consequently, undermines and hinders the development of scientific disciplines. Forensic anthropology is no exception in this trend. The present article brings up the subject of the context of forensic anthropology in Brazil to demonstrate the interconnection of the professional situation of this discipline, its structural and bureaucratic limitations and their effect on the perpetuation of human rights violation. Various aspects of daily practice of forensic anthropology in a context devoid of basic resources generate a setting that affects both the victims and their families. Despite an outstanding performance and dedication of professionals, structural limitations often substantially affect the effectiveness of their service. The present article discusses these aspects in a conceptual framework of the relation between the practice of forensic anthropology and human rights violation. In this research, Brazil serves as a case-study, an intensively studied subject that brings interpretations that can be applied in a broader context. The article aims at opening a broader, international debate that would increase the visibility of the relationship between the practice of forensic anthropology and the structure generating and/or maintaining violence in a specific economic and legislative context especially present in the countries of the so-called global South.
