Resumo: | Facial aging is known as a complex process that varies the shape and texture of thefacial area. Variations in shape include variation in craniofacial structure, while texture variation includes skin coloration, appearance of facial lines and wrinkles. Shape and texture are both considered the most common forms of facial aging patterns. Fiducial points are control points on an object that define characteristic regions with properties of interest to the application. Thus, the objective of this work is to evaluate the behavior offacial fiducial points during human aging. An evaluation was performed in a statistical manner and through classification, through the characteristics vectors obtained throughfacial fiducial points. For the accomplishment of this work, we had a social motivation,that is the aid in the search for missing persons, and another one of technical character,that is the perfection of facial recognition systems. Among the results we can highlight the behavior of increase, reduction and stabilization among some fiducial points. With regard to classification, we obtained a result of 84.29 % of correct answers when we compared the class with people under 20 years old and the class with people between 20 and 39 years old from the black men’s groups |

Variações na forma incluem variação na estrutura craniofacial, enquanto a variação na textura inclui coloração da pele, aparecimento de linhas faciais e rugas. A forma e a textura são ambas consideradas as formas mais comuns de padrões de envelhecimento facial. Já os pontos fiduciais são pontos de controle sobre um objeto que definem regiões características com propriedades de interesse à aplicação. Assim, o objetivo deste trabalho é avaliar o comportamento dos pontos fiduciais faciais durante o envelhecimento humano. Foi realizada uma avaliação de forma estatística e por meio de classificação, através dos vetores de características obtidos através dos pontos fiduciaisfaciais. Para a realização deste trabalho, tivemos uma motivação de cunho social, queé o auxílio na busca por pessoas desaparecidas, e outra de cunho técnico, que é o aperfeiçoamento de sistemas de reconhecimento facial. Dentre os resultados podemos salientar o comportamento de aumento, redução e estabilização entre alguns pontos fiduciais. No tocante a classificação chegamos a obter um resultado de 84,29% de acertos quando comparamos a classe com pessoas menores de 20 anos e a classe com pessoas entre 20 e 39 anos do grupos de homens negros.application/pdfporUniversidade Federal de GoiásPrograma de Pós-graduação em Ciência da Computação (INF)UFGBrasilInstituto de Informática - INF (RG)http://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessImagens digitaisReconhecimento facialAntropometriaClassificaçãoEnvelhecimento facialDigital imageFacial recognitionAnthropometryClassificationFacial agingCIENCIAS EXATAS E DA TERRA::CIENCIA DA COMPUTACAOAvaliação do comportamento dos pontos fiduciais faciais durante o envelhecimento humanoEvaluation of the behavior of facial fiducial points during human aginginfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesis-3303550325223384799600600600-77122667346336447683671711205811204509reponame:Repositório Institucional da UFGinstname:Universidade Federal de Goiás (UFG)instacron:UFGLICENSElicense.txtlicense.txttext/plain;
