  abstract =   "Contrast in image processing is usually dened as a ratio
               between the darkest and the brightest spots of an image. In
               this paper we introduce a different contrast denition. The
               newly introduced Global Contrast Factor (GCF) corresponds
               closer to the human perception of contrast. GCF uses
               contrasts at various resolution levels in order to compute
               overall contrast. Experiments were conducted in order to nd
               weight factors needed to calculate GCF. GCF measures
               richness of detail as perceived by a human observer, and as
               such can be used in various application areas like
               rendering, tone mapping, volume visualization, and lighting
               design",
