Interactive Extraction of High-Frequency Aesthetically-Coherent Colormaps

arXiv:2607.26025

summary

The paper introduces an interactive technique that extracts colormaps with high-frequency luminance and aesthetically coherent colors from artwork or photographs, allowing users to create visually effective colormaps for complex data visualization.

Abstract

Color transfer functions (i.e. colormaps) exhibiting a high frequency luminosity component have proven to be useful in the visualization of data where feature detection or iso-contours recognition is essential. Having these colormaps also display a wide range of color and an aesthetically pleasing composition holds the potential to further aid image understanding and analysis. However producing such colormaps in an efficient manner with current colormap creation tools is difficult. We hereby demonstrate an interactive technique for extracting colormaps from artwork and pictures. We show how the rich and careful color design and dynamic luminance range of an existing image can be gracefully captured in a colormap and be utilized effectively in the exploration of complex datasets
