Intrinsic imaging lighting
There exist a number of automatic priors that affect different aspects of the decomposition: 1. Shading: The initial techniques that addressed the intrinsic decomposition problem relied on theories of the human vision which relate local changes of intensity with either changes in reflectance or … See more Another set of techniques rely on automatic priors and user intervention. The first method to incorporate this kind of input into an optimization framework was Bousseau et al.
