However, there are still very few tools for light field editing, and the interfaces to create those edits remain largely unexplored. Given the extended dimensionality of light field data, it is not clear what the most intuitive interfaces and optimal workflows are, in contrast with well-studied two-dimensional (2-D) image manipulation software. In this work, we provide a detailed description of subjects' performance and preferences for a number of simple editing tasks, which form the basis for more complex operations. We perform a detailed state sequence analysis and hidden Markov chain analysis based on the sequence of tools and interaction paradigms users employ while editing light fields. These insights can aid researchers and designers in creating new light field editing tools and interfaces, thus helping to close the gap between 4-D and 2-D image editing. info:eu-repo/grantAgreement/ES/MINECO/TIN2016-78753-P This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 682080-CHAMELEON info:eu-repo/grantAgreement/EC/H2020/682080/EU/Intuitive editing of visual appearance from real-world datasets/CHAMELEON info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 4.361 2017 ENGINEERING, ELECTRICAL & ELECTRONIC 30 / 260 = 0.115 2017 Q1 T1 1.331 2017 Signal Processing 2017 Q1 Electrical and Electronic Engineering 2017 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0001-9000-0466 Jarabo, Adrian (orcid)0000-0003-0060-7278 Masia, Belen Universidad de Zaragoza (orcid)0000-0002-7503-7022 Gutierrez, Diego Universidad de Zaragoza 5007 570 Universidad de Zaragoza Dpto.
