The reduced number of inks available define the printer's limited gamut, creating distortions in the printed appearance that are hard to control. Gamut mapping refers to the process of bringing an out-of-gamut material appearance into the printer's gamut, while minimizing such distortions as much as possible. We present a novel two-step gamut mapping algorithm that allows users to specify which perceptual attribute of the original material they want to preserve (such as brightness, or roughness). In the first step, we work in the low-dimensional intuitive appearance space recently proposed by Serrano et al. [SGM*16], and adjust achromatic reflectance via an objective function that strives to preserve certain attributes. From such intermediate representation, we then perform an image-based optimization including color information, to bring the BRDF into gamut. We show, both objectively and through a user study, how our method yields superior results compared to the state of the art, with the additional advantage that the user can specify which visual attributes need to be preserved. Moreover, we show how this approach can also be used for attribute-preserving material editing. 000078313 536__ $$9info:eu-repo/grantAgreement/ES/MINECO/TIN2016-79710-P$$9info:eu-repo/grantAgreement/ES/MINECO/TIN2016-78753-P$$9This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 682080-CHAMELEON$$9info:eu-repo/grantAgreement/EC/H2020/682080/EU/Intuitive editing of visual appearance from real-world datasets/CHAMELEON 000078313 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000078313 590__ $$a2.046$$b2017 000078313 591__ $$aCOMPUTER SCIENCE, SOFTWARE ENGINEERING$$b22 / 104 = 0.212$$c2017$$dQ1$$eT1 000078313 592__ $$a0.597$$b2017 000078313 593__ $$aComputer Networks and Communications$$c2017$$dQ1 000078313 593__ $$aComputer Graphics and Computer-Aided Design$$c2017$$dQ2 000078313 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000078313 700__ $$0(orcid)0000-0002-5169-7042$$aSerrano, Ana$$uUniversidad de Zaragoza 000078313 700__ $$0(orcid)0000-0002-7503-7022$$aGutierrez, Diego$$uUniversidad de Zaragoza 000078313 700__ $$0(orcid)0000-0003-0060-7278$$aMasia, Belen$$uUniversidad de Zaragoza 000078313 7102_ $$15002$$2305$$aUniversidad de Zaragoza$$bDpto.
