This work presents an efficient interaction paradigm that approximates any per-pixel magnitude from a few user strokes by propagating the sparse user input to each pixel of the image. The propagation scheme is based on a linear least-squares system of equations which represents local and neighboring restrictions over superpixels. After each user input, the system responds immediately, propagating the values and applying the corresponding filter. Our interaction paradigm is generic, enabling image editing applications to run at interactive rates by changing just the image processing algorithm, but keeping our proposed propagation scheme. We illustrate this through three interactive applications: depth of field simulation, dehazing and tone mapping. 000071167 536__ $$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/DPI2015-69376-R$$9info:eu-repo/grantAgreement/ES/MINECO/DPI2015-65962-R$$9This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 682080-CHAMELEON$$9info:eu-repo/grantAgreement/EC/H2020/682080/EU/Intuitive editing of visual appearance from real-world datasets/CHAMELEON$$9info:eu-repo/grantAgreement/ES/DGA/T04 000071167 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000071167 590__ $$a1.036$$b2017 000071167 591__ $$aCOMPUTER SCIENCE, SOFTWARE ENGINEERING$$b67 / 104 = 0.644$$c2017$$dQ3$$eT2 000071167 592__ $$a0.401$$b2017 000071167 593__ $$aComputer Graphics and Computer-Aided Design$$c2017$$dQ2 000071167 593__ $$aSoftware$$c2017$$dQ2 000071167 593__ $$aComputer Vision and Pattern Recognition$$c2017$$dQ2 000071167 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000071167 700__ $$0(orcid)0000-0002-7580-9037$$aMurillo, Ana C.$$uUniversidad de Zaragoza 000071167 700__ $$0(orcid)0000-0002-8160-7159$$aMuñoz, Adolfo$$uUniversidad de Zaragoza 000071167 7102_ $$15007$$2520$$aUniversidad de Zaragoza$$bDpto.
