Separating Reflection Components of Smooth Metallic Surface Using Special Random Sampling Method

In smooth metallic surfaces, highlights are very strong and illuminant shapes are often observed as specular reflections. In order to separate specular reflection components and diffuse reflection components on smooth metallic surfaces, a set of real images are taken under various lighting conditions and Special Random Sampling Method is introduced to regenerate diffuse reflection components as well as to obtain specular reflection components. Experimental results show that diffuse reflection components and specular reflection components can be effectively separated in realistic images of smooth metallic surfaces using this technique.
