The Retinex perception theory tries to mimic the human ability to cope with the high dynamic range of natural scenes. In 1986 E. Land proposed a formulation of this model in terms of a Center/Surround operation involving two steps, a local adaptation and a global transform. This model gave rise to the so-called Center/Surround tone-mapping algorithms. In this paper we unify the different Center/Surround algorithms proposed in the literature using a common framework and analyze several possibilities for the local and global operations involved.
