Aging effects on face images by varying vertical feature placement and transforming face shape

In this paper we have investigated the effect of three kinds of facial manipulations on the perceived age. For this aim three experiments to assess the influence of facial manipulation were conducted, in which the shape of face was manipulated using the cardioidal strain transformation, the vertical placements of facial features were manipulated, and the facial shape was locally distorted so as to reflect the actual facial changes from twenty age to fifty age based on the report by Burt and Perrett[4]. In each experiment, the original facial images were selected in five age categories, elementary school, junior high school, high school, twenties, and over fifty, comparing the effect of graphical transformation on the perceived age in different age categories. We have discussed that these geometrical transformations of face have the aging effect and the aging effect of the five age categories had been different with each other.
