This paper investigates the problem of object surface reflectance modeling, which is sometimes referred to as inverse reflectometry, for photorealistic rendering and effective multimedia applications. A number of methods have been developed for estimating object surface reflectance properties in order to render real objects under arbitrary illumination conditions. However, it is still difficult to densely estimate surface reflectance properties in real-time. This paper describes a new method for real-time estimation of the non-uniform surface reflectance properties in the inverse rendering framework. Experiments are conducted in order to demonstrate the usefulness and the advantage of the proposed methods through comparative study.
