Estimating spectral reflectance using highlights

摘要

A new algorithm is presented for estimating the spectral reflectance of a surface from a colour image using highlights. The technique is based on detailed reflectance models and is more general than existing techniques. An estimate of spectral reflectance is useful for surface recognition and characterization because it is intrinsic to the material, i.e. it does not depend on illumination conditions. Experimental results obtained by applying the algorithm to colour images are presented.
