Dude, Everyone Wants Pattern Analysis Tools (DEWPAT): Tools for measuring visual pattern diversity from digital images

O_LIExploring the diversity and function of complex colour patterns is a fundamental interest in ecology and evolutionary biology, but progress on many questions is limited by our ability to quantify diverse visual patterns. We address this problem by introducing Dude, Everyone Wants Colour Pattern Analysis Tools (DEWPAT), a Python package for characterizing multidimensional pattern complexity. C_LIO_LIDEWPAT is a flexible framework designed to extract a diversity of components of visual pattern complexity from standard RGB and multispectral images, including entropy (information content), average gradient magnitude (edge content), high frequency content (detail granularity), generalized variance (heterogeneity), and patch dissimilarity. DEWPAT offers optional image transformation functionality, including blurring to model receiver acuity and segmentation to reduce noise. C_LIO_LIFunctions in this package return both quantitative measurements and graphical representations of color and pattern diversity. We demonstrate DEWPATs key functions and applications with three empirical examples (longhorn beetles, anole lizards, and flowers). C_LIO_LIDEWPAT has the potential to quantitatively characterize previously intractable pattern phenotypes in ways that make their features available for biological analysis. C_LI
