Abstract :
A comprehensive model that predicts reflectance from rough diffuse surfaces is presented. It is shown that diffuse reflectance from rough surfaces increases as the viewing direction approaches the source direction. This is in contrast to Lambertian surfaces, where radiance is independent of the viewing direction. The new model is a generalization of the Lambertian model, and has significant implications for machine vision, graphics, and remote sensing
