Ítem Effects of diffuse and specular reflections on the perceived age of facial skin(Springer Verlag, 2012-05-01) Arce Lopera, Carlos AlbertoAge perception is a better biomarker of skin aging than chronological age. However, the optical cues that determine the perception of human skin age are difficult to assess given the complex interactions between light and the multi layered structure of the skin. The aim of the present study is to clarify the independent contribution of both diffuse and specular reflection components to the skin age perceptionÍtem Image statistics on the age perception of human skin(Wiley, 2013-02-01) Arce Lopera, Carlos AlbertoRecent research on the age-dependent changes of facial skin has analyzed their correlation with changes in image and colorimetric properties using mainly first- and second-order statistics. The aim of this study is to reveal the importance of third-order statistics and relate those image properties to skin age perception.
