A quick method for synthesizing photorealistic color images under various illumination conditions
Li Shen, N. Babagushi, Tadahiro Kitahashi · 2002
We propose a fast method to synthesize realistic images under novel lighting directions using three color images. In the method, we use a look-up table procedure to estimate the surface orientations, instead of complex computations. Moreover, we explain a way to separate the diffuse and specular reflection components from the three color images.
