Face databases have assumed an important role in a variety of clinical and applied research domains. However, the number of datasets accessible to the scientific community is limited and the knowledge of their existence may be concealed from a wider range of specialists. In the present paper we introduce a sizeable dataset of 3D facial scans - FIDENTIS 3D Face Database (F3D-FD or FIDENTIS Database), which is accompanied by basic demographic and descriptive data. The database is structured according to recorded subjects, and comprises single-scan entries as well as a smaller number of multiscan entries. The multi-scan entries vary in the time passed between recording sessions and in the devices employed to collect the 3D data. The total number of 2476 individuals puts our database within the category of large-scale databases. The 3D scans are accessible through a web-based interface at www. fidentis.cz. A licensed version of the database is available to interested parties upon signing a license agreement. Because of its varied composition, and low target-specificity the database has capacity to be of great assistance for the worldwide research community.

Background and aim: The effect of socio-economic factors (living conditions) and parental smoking habits on development of facial morphology and body measurements was studied on a longitudinal Czech sample of 25 girls and 25 boys. Subjects and methods: A set of studied digitalized photographs taken from 0.5 to 18 years in intervals of 6 months originated in the Brno Longitudinal Study. Facial shape changes of sub-adult participants were described using a configuration of 27 landmarks and further studied by using methods of geometric morphometric and multivariate statistics. In order to localize growth-related shape changes within the face, the studied region was divided into upper, middle and lower facial units and analyzed separately. Results and conclusion: The results show that in the course of ontogenesis there is a strong correlation between facial shape change and body measurements, height included (r=0.10 and r=0.24 in boys and in girls, respectively). The pubertal spurt of the facial shape change rate was revealed at 10.5 years in girls and at 11.5 years in boys. The earlier onset of the pubertal rate increase in facial shape changes in boys was associated with records of poor living conditions. In addition, the mother’s smoking habits were linked to a noticeable facial shape change.

AbstraktAntropologická analýza lidských kosterních nálezů je podmíněná jejích celistvostí a úplností. Čas-to je kosterní nález předáván k antropologickému zpracování ve fragmentárním, nekompletním anebo deformovaném stavu a před zhodnocením je třeba jej zrestaurovat či zrekonstruovat. Moderní počítačové metody umožňují neúplné kosterní nálezy virtuálně restaurovat a rekonstruovat a výsledný virtuální model podrobit odbornému zkoumání s počítačovou podporou. V této studii byly kvantifikovány rozdíly, které do antropologického zpracování vnáší restaurační a rekonstrukční postupy. Digitální 3D modely lidských lebek upravené virtuálními postupy byly srovnány mezi dvě-ma odborníky i v rámci každého z nich. Získané výsledky naznačují, že se zvyšující se náročností virtuální restaurace se zvyšují i rozdíly mezi modely, které vytvořili odlišní hodnotitelé. Na výsledky virtuálních postupů má současně negativní vliv velikost lomných ploch úlomků, které jsou k sobě během restaurace přikládány.

Yet, human skeletal remains are frequently uncovered fragmented, incomplete and/or distorted. In order to utilize standard methods the employment of a restoration or reconstruction technique becomes the first step. Recently, advances made in digital technologies gave origin to virtual restoration and reconstruction approaches. In the present paper, reliability of virtual restoration and reconstruction procedures was tested in order to quantify intra-and inter-operator error. The acquired results showed that for restored models the inter-operator differences increased with the complexity of the virtual restoration procedure. Furthermore, the results were shown to be affected by the size of the complementary contact walls used to virtually re-assemble the fragmented bones.
