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.

PosterChild：混合感知艺术海报化

海报化是一种艺术效果，可将连续图像转换为具有平滑边界的恒定颜色区域，通常具有艺术性重新着色的调色板。艺术海报化极其耗时且乏味。我们引入了一种混合感知算法，用于生成带有基于调色板的艺术重新着色控制的分色图像。我们的算法会自动提取调色板，然后使用多标签优化来根据该调色板查找混合颜色区域。我们使用频率引导的中值滤波来平滑远离图像细节的边界。我们通过比较用户研究来评估我们的算法，并展示其生成各种输入的引人注目的海报的能力。我们的参数提供艺术控制，并在分色预处理后实现有凝聚力的实时重新着色。
