Cosine lobe based relighting from gradient illumination photographs
Graham Fyffe · 2009
Image-based relighting is a powerful technique for synthesizing images of a scene under novel illumination conditions, based on a set of input photographs. While successful relighting methods exist, they either require many photographs [Debevec et al. 2000], or operate on a limited class of materials or illumination conditions [Ma et al. 2007][Ramamoorthi 2006].
