RESUMO
O objetivo dessa pesquisa foi gerar, por meio de técnica de computação gráfica denominada morphing, faces prototípicas masculinas e femininas a partir de amostras de pessoas que se autodeclaram brancas, pardas e pretas na região de Ribeirão Preto (SP). A cada face prototípica foram utilizadas 64 imagens de faces de voluntários. As faces prototípicas e as faces que as compuseram tiveram a tipicidade de sua cor ou raça julgada por terceiros. Os julgamentos indicaram uma concordância entre a cor/raça-autodeclarada e a heteroatribuída o que indica que os protótipos são representativos de suas respectivas categorias de cor/raça. Discute-se como as faces prototípicas podem ser empregadas em pesquisas básicas e aplicadas em percepção e reconhecimento de faces.
ABSTRACT
The goal of this study was to generate male and female prototypical faces, by morphing technique, from faces of people who were self-declared as white, "mixed race" and black in Ribeirão Preto-SP. Each prototypical face was generated from 64 face images of volunteers. Another sample of volunteers judged the typicality of color/race of the prototypical faces and the faces that composed them. The results suggested a concordance between the self-declared color/race and the judgments, indicating that the prototypical faces are representative of their respective categories of color/race. Applications of the prototypical faces in studies of face perception and face recognition were discussed.
