Paper Abstract

The human figure with skin colors is always the focus of the people watching images displayed on the display devices like LCDs. The human perception of skin colors is always influenced by surrounding colors due to simultaneous color contrast effect. This paper presents a scheme for analyzing the perception shift of some representative skin colors which are arranged to be against a set of pre-selected background colors. The shift in perception is quantified by the differences of gamma parameters that characterize the GOG models of the skin color surrounded by the mid-gray color and the skin color surrounded by a specified background color, while both skin colors give the same appearance. With the results of the analysis on the gamma deviation of the reference skin colors, a scheme for correcting skin colors has been developed such that the appearance of the skin color against any background color can be very close to that of the same skin color against the mid-gray color. The results of subjective experiments indicate that the proposed scheme is feasible in removing the effect simultaneous effect.
