Kinship verification and recognition based on handcrafted and deep learning feature-based techniques

Background and Objectives Kinship verification and recognition (KVR) is the machine’s ability to identify the genetic and blood relationship and its degree between humans’ facial images. The face is used because it is one of the most significant ways to recognize each other. Automatic KVR is an interesting area for investigation. It greatly affects real-world applications, such as searching for lost family members, forensics, and historical and genealogical studies. This paper presents a comprehensive survey that describes KVR applications and kinship types. It presents a literature review of current studies starting from handcrafted passing through shallow metric learning and ending with deep learning feature-based techniques. Furthermore, kinship mostly used datasets are discussed that in turn open the way for future directions for the research in this field. Also, the KVR limitations are discussed, such as insufficient illumination, noise, occlusion, and age variations problems. Finally, future research directions are presented, such as age and gender variation problems. Methods We applied a literature survey methodology to retrieve data from academic databases. An inclusion and exclusion criteria were set. Three stages were followed to select articles. Finally, the main KVR stages, along with the main methods in each stage, were presented. We believe that surveys can help researchers easily to detect areas that require more development and investigation. Results It was found that handcrafted, metric learning, and deep learning were widely utilized in kinship verification and recognition problem using facial images. Conclusions Despite the scientific efforts that aim to address this hot research topic, many future research areas require investigation, such as age and gender variation. In the end, the presented survey makes it easier for researchers to identify the new areas that require more investigation and research.

ГРАМАТИЧНИ ОСОБЕНОСТИ НА НАЙ-НОВАТА СУБСТАНТИВНА ЛЕКСИКА В БЪЛГАРСКИЯ ЕЗИК / GRAMMATICAL PECULIARITIES OF THE NEW SUBSTANTIVE LEXIS IN THE BULGARIAN LANGUAGE

The article discusses some grammatical peculiarities of the substantive neologisms in the Bulgarian language and analyzes the plural forms of some new one-syllable and multisyllable nouns that violate the grammatical rules. In addition, the authors address newly-formed pluralia tantum nouns and analyze examples of gender variation of some substantive neologisms. Keywords: neologisms, nouns, plural forms, variability, gender, Bulgarian language

Autisme en genderidentiteit: aanbevelingen voor de praktijk

The present essay describes genderidentification in autism spectrum disorder, as well as autism spectrum disorder in gender variation or dysphoria. Authors argue the importance of determining the individual’s social and emotional development before conferring meaning and before deciding on potentially irreversible treatment trajectories.

Radiologic Evaluation of Odontometric and Osteologic Traits for Gender Determination in Adult Ethnic Tamil Population

Background: Odontometric and osteologic trait have always served as an excellent resource in anthropological, genetic, odontologic, and forensic investigations. Traits: The aim of this study was to find the most reliable method for gender determination by correlating both the odontometric and osteologic variables. Materials and Methods: A retrospective study was conducted using digital panoramic radiographs of 400 individuals (200 males and 200 females) with age ranging from 20 to 50 years. Standardized digital panoramic radiographs of patients taken as part of pretreatment planning for implants, extractions of third molars, and for periodontal diseases were selected from the archives. Measurements were done using IMAGE Pro software. Results: Mesiodistal width of 17–47 exhibited significant gender variation. Osteologic parameters such as ramus dimension and the gonial angle also showed significant gender variation and the mandibular asymmetry was significant in both the genders. Conclusion: Correlation of the two group of traits showed strong positive predictive values attributable for gender determination.

PATTERN OF DENTAL OCCLUSION IN A POPULATION OF URHOBO SUBJECTS IN ABRAKA, NIGERIA

The closing order of superior and inferior teeth whilst chewing or at relaxation is termed dental occlusion. Literature exploration divulged want of information on dental occlusion among the Urhobos in Delta State, Nigeria. The endeavour of this work was to consider varied dental occlusion patterns and explore gender variation in dental occlusion patterns amongst the Urhobo tribal cluster in Abraka, Nigeria. Totality of 384 citizens (200 females and 184 males) who were within 15-30 years age set were engaged in this inquisition. The gender gap is a depiction of the male/female scattering in the appraised populace. Records on dental occlusion patterns were composed by having the subjects’ bite, gulp saliva, occlude and open their mouths. The connexion of the upper and lower teeth was labelled as mild overbite, edge to edge bite, negative bite or severe overbite as specified by Eveleth in 1972. Inferential statistics were explored using chi-square by means of Statistical Package for the Social Sciences (SPSS), version 23 and significance level were determined by p < .05. The dental occlusion patterns observed were mild overbite 168 (43.4%), edge-edge bite 146 (38.2%), severe overbite 70 (18.4%) with no negative overbite 0 (0%). The gender dissimilarity in dental occlusion pattern was not notable (p>.05). Mild overbite is preponderant and severe overbite is infrequent amid the Urhobos in Abraka, Nigeria.
