Analysis of multiple reflection components

Abstract

An algorithm is proposed for the detection and separation of specularity from Lambertian reflectance using multiple image frames from different viewpoints. The algorithm is based on the physical model of the multiple reflection mechanism in which the appearance of specularity varies depending on viewing direction while that of Lambertian reflection does not. The approach is to move camera sensors actively and to obtain as many image frames as possible. Experimental results are presented to show the efficiency of the algorithm.<>
