Image-Based Relighting - Luminance Mapping based on lighting functions

Abstract

The paper proposes a method for generating a sequence of images with smooth transition of illumination from two input images with different lighting conditions. Our relighting approach is image?based, such as the light field rendering. We store the luminances (pixel RGB values) into “ lighting functions ” consisting of a couple of parameters related on normal vectors. Images with different light positions are rendered by interpolating the luminances retrieved from the lighting functions. The proposed method is a promising technique for many applications requiring a scene with variety of lighting effects, such as movies, TV games, and so on.
