A Theoretical Framework for Visual Weight: Contrast, Size, and Edge Sharpness as Candidate Determinants of Perceived Dominance in Static Images

This preprint presents a theoretical framework for visual weight in static images. The framework proposes that perceived compositional dominance depends on three candidate variables: contrast relative to a perceptually defined ground (“canvas”), fractional area, and edge transition sharpness (“hardness”). These variables are combined multiplicatively and embedded within a competitive architecture based on divisive normalization. A provisional chromatic extension accounts for interactions between color and luminance. The manuscript formalizes a concept long discussed qualitatively in art and design practice and derives falsifiable predictions for future empirical testing.
