Introduction
Art complexity modeling is an interdisciplinary field that analyzes and quantifies the structural, perceptual, and conceptual complexity of artworks. By applying mathematical principles, computational methods, and aesthetic theory, researchers can develop models that help understand artistic creation, perception, and evaluation. These models provide frameworks for analyzing historical trends, comparing artistic styles, informing computational creativity, and enriching art education. This cheatsheet offers a comprehensive overview of key approaches to modeling complexity in art, from quantitative metrics to perceptual frameworks and practical applications.
