      Altıok, Ozan Can; Sezgin, Tev k Metin (Association for Computing Machinery, Inc (ACM), 2017)
      From a user interaction perspective, speech and sketching make a good couple for describing motion. Speech allows easy speci cation of content, events and relationships, while sketching brings in spatial expressiveness. ...
    • Combining Sketch and Tone for Pencil Drawing Production 

      Lu, Cewu; Xu, Li; Jia, Jiaya (The Eurographics Association, 2012)
      We propose a new system to produce pencil drawing from natural images. The results contain various natural strokes and patterns, and are structurally representative. They are accomplished by novelly combining the tone and ...
    • Consistent Stylization and Painterly Rendering of Stereoscopic 3D Images

    • Data-Driven Iconification 

      Liu, Yiming; Agarwala, Aseem; Lu, Jingwan; Rusinkiewicz, Szymon (The Eurographics Association, 2016)
      Pictograms (icons) are ubiquitous in visual communication, but creating the best icon is not easy: users may wish to see a variety of possibilities before settling on a final form, and they might lack the ability to draw ...

    • Drawing Characteristics for Reproducing Traditional Hand-Made Stippling 

      Martín, Domingo; Sol, Vicente del; Romo, Celia; Isenberg, Tobias (The Eurographics Association, 2015)
      We contribute an in-depth analysis of the characteristics of traditional stippling and relate these to common practices in NPAR stippling techniques as well as to the abilities and limitations of existing printing and ...
    • Edge- and substrate-based effects for watercolor stylization 

      Montesdeoca, Santiago E.; Seah, Hock Soon; Bénard, Pierre; Vergne, Romain; Thollot, Joëlle; Rall, Hans-Martin; Benvenuti, Davide (Association for Computing Machinery, Inc (ACM), 2017)
      We investigate characteristic edge- and substrate-based effects for watercolor stylization. These two fundamental elements of painted art play a significant role in traditional watercolors and highly influence the pigment's ...
    • ELASTIFACE: Matching and Blending Textured Faces 

      Zell, Eduard; Botsch, Mario (ACM, 2013)
      In this paper we present ELASTIFACE, a simple and versatile method for establishing correspondence between textured face models, either for the construction of a blend-shape facial rig or for the exploration of new characters ...
    • Example-Based Brushes for Coherent Stylized Renderings 

      Zheng, Ming; Milliez, Antoine; Gross, Markus; Sumner, Robert W. (Association for Computing Machinery, Inc (ACM), 2017)
      Painterly stylization is the cornerstone of non-photorealistic render- ing. Inspired by the versatility of paint as a physical medium, exist- ing methods target intuitive interfaces that mimic physical brushes, providing ...
    • Front- and Backmatter: NPAR 2017 

      Holger Winnemoeller; Lyn Bartram (Association for Computing Machinery, Inc (ACM), 2017)
    • A generic framework for the structured abstraction of images 

      Faraj, Noura; Xia, Gui-Song; Delon, Julie; Gousseau, Yann (Association for Computing Machinery, Inc (ACM), 2017)
      Structural properties are important clues for non-photorealistic representations of digital images. erefore, image analysis tools have been intensively used either to produce stroke-based render- ings or to yield abstractions ...
    • Hybrid-Space Localized Stylization Method for View-Dependent Lines Extracted from 3D Models 

      Cardona, Luis; Saito, Suguru (The Eurographics Association, 2015)
      We propose a localized stylization method that combines object-space and image-space techniques to locally styl- ize view-dependent lines extracted from 3D models. In the input phase, the user can customize a style and ...
    • Interactive NPAR: What Type of Tools Should We Create? 

      Isenberg, Tobias (The Eurographics Association, 2016)
      I argue that we need to increase our consideration of the interaction that is possible and/or needed for the NPAR algorithms we develop. Depending on the application domain of a given algorithmic contribution, different ...
    • 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)
