Paper Abstract

This paper describes a method for estimating a reflection model from a color image of an object taken by a multi-band CCD camera. The Torrance-Sparrow model is used for modeling light reflection on an object surface. We propose algorithms for estimating model parameters from a single image by the multi-band CCD camera. To estimate the surface roughness, we propose the use of the brightness image and the reflectance map in the neighborhood of a highlight peak point. An algorithm is presented for finding a particular solution of the surface orientation. The feasibility of the method is demonstrated in an experiment using a painted object. The estimation accuracy of the whole model is confirmed based on computer graphics images.
