Abstract
Posterization is an artistic effect which converts continuous images into regions of constant color with smooth boundaries, often with an artistically recolored palette. Artistic posterization is extremely time-consuming and tedious. We introduce a blend-aware algorithm for generating posterized images with palette-based control for artistic recoloring. Our algorithm automatically extracts a palette and then uses multi-label optimization to find blended-color regions in terms of that palette. We smooth boundaries away from image details with frequency-guided median filtering. We evaluate our algorithm with a comparative user study and showcase its ability to produce compelling posterizations of a variety of inputs. Our parameters provide artistic control and enable cohesive, real-time recoloring after posterization pre-processing.
