Image-pair-based anisotropic material modeling

Abstract

We present a method for modeling anisotropic materials with only two images taken by an ordinary camera, one under diffuse light which we call texture image, and the other under point light named hightlighted image. First we decompose the input images into reflectance image and illumination image. Then we use the intrinsic images to obtain the reflectance property and geometry information of the material, including a group of BRDF parameters, an orientation field and a height field. Then images can be rendered with these information under new lighting and viewing conditions.
