Abstract

A new gloss sensing system is proposed. A spatial filter G representing the human retina function is utilized for the extraction of glossiness. The light intensity distribution h_in of the object is convoluted with the spatial filter G. In this study, the filter´s size of G increases with the light intensity of the object. Using the maximum value H_max of the distribution obtained by the convolution of h_in with G, the authors give a new definition G_f of glossiness. New glossiness G_f extracted from the various objects with the radii of 4~∞ mm corresponds well with psychological glossiness over the wide gloss range
