Abstract:
Reflectance of an object’s surface plays an important role in image synthesis. Several reflection models have been proposed to realize realistic object representation, but the reflectance parameters are difficult to determine appropriately. Sato et al. [Sato et al. 1997] proposed a method to measure reflectance properties of real objects using the shape information and captured images. For more realistic image generation, it is necessary to measure the roughness parameters of an object’s surface from real images. Previous work has been done to obtain bump maps from real images [Rushmeier et al. 1997; Lefebvre and Poulin 2000]. In this paper, we propose a method to model roughness as bump parameters using distribution functions.
