Even the sophisticated autoregre ssive model struggles to maintain long-distance color consistency due to t he fragility of sequential dependence.\nTo overcome this challenge, we pro pose a novel colorization framework that disentangles color multimodality and structure consistency through global color anchors, so that both aspec ts could be learned effectively. Our key insight is that several carefully located anchors could represent the color distribution of an image approx imately, and conditioned on the anchor colors, we can predict the image co lor in a deterministic manner by leveraging the internal correlation. To t his end, we construct a colorization model with dual branches, where the c olor modeler predicts the color distribution for anchor color representati on, and the color generator predicts the pixel colors by referring the sam pled anchor colors. Importantly, the anchors are located under two princip les: color independence and global coverage, which is realized with cluste ring analysis on the deep color features. To simplify the computation, we creatively adopt soft superpixel segmentation to reduce the image primitiv es, which still nicely reserves the reversibility to pixel-wise representa tion. Extensive experiments show that our method achieves notable superior ity over various mainstream frameworks in perceptual quality. Thanks to an chor-based color representation, our model has the flexibility to support diverse and controllable colorization as well.\n\nRegistration Category: F ULL ACCESS, ON-DEMAND ACCESS\n\nLanguage: ENGLISH\n\nFormat: IN-PERSON, ON -DEMAND URL:https://sa2022.siggraph.org/en/full-program/?id=papers_130&sess=sess15 9 END:VEVENT END:VCALENDAR
