This database consists of the following sections which are publicly available for research purposes.BRDF(bidirectional reflectance distribution function)databasewith reflectance measurements for over 60 different samples, each observed with over 200 different combinations of viewing and illumination directions.BRDF parameter databasewith fitting parameters from two recent BRDF models: theOren-Nayarmodel and theKoenderink et al.representation. These BRDF parameters can be directly used for both image analysis and image synthesis.BTF(bidirectional texture function)databasewith image textures from over 60 different samples, each observed with over 200 different combinations of viewing and illumination directions.Related publications:K.J.
