Computing Isotropic Local Contrast from Oriented Pyramid Decompositions

Computing Isotropic Local Contrast from Oriented Pyramid Decompositions
Working with contrast instead of luminance can facilitate numerous image processing and analysis tasks. Unfortunately, a common definition of contrast suitable for all situations does not exist. In this paper we review existing contrast definitions for natural images and propose a new isotropic contrast measure, which is computed from oriented filters. We investigate some of its properties and apply it to natural images.
