    • Map Style Formalization: Rendering Techniques Extension for Cartography 

      Christophe, Sidonie; Duménieu, Bertrand; Turbet, Jérémie; Hoarau, Charlotte; Mellado, Nicolas; Ory, Jérémie; Loi, Hugo; Masse, Antoine; Arbelot, Benoit; Vergne, Romain; Brédif, Mathieu; Hurtut, Thomas; Thollot, Joëlle; Vanderhaeghe, David (The Eurographics Association, 2016)
      Cartographic design requires controllable methods and tools to produce maps that are adapted to users' needs and preferences. The formalized rules and constraints for cartographic representation come mainly from the ...

    • The Markov Pen: Online Synthesis of Free-Hand Drawing Styles 

      Lang, Katrin; Alexa, Marc (The Eurographics Association, 2015)
      Learning expressive curve styles from example is crucial for interactive or computer-based narrative illustrations. We propose a method for online synthesis of free-hand drawing styles along arbitrary base paths by means ...

    • Mixed Illumination Analysis in Single Image for Interactive Color Grading 

      Duchêne, Sylvain; Aliaga, Carlos; Pouli, Tania; Pérez, Patrick (Association for Computing Machinery, Inc (ACM), 2017)
      Colorists often use keying or rotoscoping tools to access and edit particular colors or parts of the scene. Although necessary, this is a time-consuming and potentially imprecise process, as it is not possible to fully ...

    • Modeling Go: A mobile sketch-based modeling system for extracting objects 

      Lai, Chun-An; Chiang, Pei-Ying (Association for Computing Machinery, Inc (ACM), 2017)
      This article presents an easy to use mobile application which allows users to create 3D digital copies of their interested objects anywhere and anytime. An advanced 3-sweep modeling technique is developed to construct 3D ...

    • Neural Style Transfer: A Paradigm Shift for Image-based Artistic Rendering? 

      Semmo, Amir; Isenberg, Tobias; Döllner, Jürgen (Association for Computing Machinery, Inc (ACM), 2017)
      In this meta paper we discussimage-based artistic rendering (IB-AR)based onneural style transfer(NST) and argue, while NST may represent a paradigm shift for IB-AR, that it also has to evolve as an interactive tool that ...

    • No Photos Harmed / Growing Paths from Seed - An Exhibition 

      Colton, Simon; Ferrer, Blanca Perez (The Eurographics Association, 2012)
      We report on an exhibition centered around a dialogue between a Computational Creativity researcher presenting artwork generated by a computer program and a classically trained artist taking inspiration from the computational ...

    • Patternista: Learning Element Style Compatibility and Spatial Composition for Ring-based Layout Decoration 

      Phan, Huy Quoc; Lu, Jingwan; Asente, Paul; Chan, Antoni B.; Fu, Hongbo (The Eurographics Association, 2016)
      Creating aesthetically pleasing decorations for daily objects is a task that requires deep understanding of multiple aspects of object decoration, including color, composition and element compatibility. A designer needs a ...

    • Pigment-Based Recoloring of Watercolor Paintings 

      Aharoni-Mack, Elad; Shambik, Yakov; Lischinski, Dani (Association for Computing Machinery, Inc (ACM), 2017)
      The color palette used by an artist when creating a painting is an important tool for expressing emotion, directing attention, and more. However, choosing a palette is an intricate task that requires considerable skill and ...

    • Pixelated Image Abstraction 

      Gerstner, Timothy; DeCarlo, Doug; Alexa, Marc; Finkelstein, Adam; Gingold, Yotam; Nealen, Andrew (The Eurographics Association, 2012)
      We present an automatic method that can be used to abstract high resolution images into very low resolution outputs with reduced color palettes in the style of pixel art. Our method simultaneously solves for a mapping of ...

    • Pixelating Vector Line Art 

      Inglis, Tiffany C.; Kaplan, Craig S. (The Eurographics Association, 2012)
      Creating pixel art is a laborious process that requires artists to place individual pixels by hand. Although many image editors provide vector-to-raster conversions, the results produced do not meet the standards of pixel ...

    • Preface and Table of Contents 

      Forrester Cole and Cindy Grimm (ACM, 2013)

    • Quantifying Visual Abstraction ality for Stipple Drawings 

      Spicker, Marc; Hahn, Franz; Lindemeier, Thomas; Saupe, Dietmar; Deussen, Oliver (Association for Computing Machinery, Inc (ACM), 2017)
      We investigate how the perceived abstraction quality of stipple illustrations is related to the number of points used to create them. Since it is di cult to nd objective functions that quantify the visual quality of such ...

    • Rasterizing and antialiasing vector line art in the pixel art style 

      Inglis, Tiffany C.; Vogel, Daniel; Kaplan, Craig S. (ACM, 2013)
      Pixel artists rasterize vector shapes by hand to minimize artifacts at low resolutions and emphasize the aesthetics of visible pixels. We describe Superpixelator, an algorithm that automates this process by rasterizing ...

    • Real-Time Panorama Maps 

      Brown, S. Alex; Samavati, Faramarz (Association for Computing Machinery, Inc (ACM), 2017)
      Panorama maps are stylized paintings of terrain often seen at tourist destinations. They are difficult to create since they are both artistic and grounded in real geographic data. In this paper we present techniques for ...

    • Semi-Automatic Digital Epigraphy from Images with Normals 

      Berkiten, Sema; Fan, Xinyi; Rusinkiewicz, Szymon (The Eurographics Association, 2015)
      We present a semi-automated system for converting photometric datasets (RGB images with normals) into geometry-aware non-photorealistic illustrations that obey the common conventions of epigraphy (black-and-white archaeological ...
