    • Benchmarking Non-Photorealistic Rendering of Portraits 

      Rosin, Paul L.; Mould, David; Berger, Itamar; Collomosse, John; Lai, Yu-Kun; Li, Chuan; Li, Hua; Shamir, Ariel; Wand, Michael; Wang, Tinghuai; Winnem, Holger (Association for Computing Machinery, Inc (ACM), 2017)
      We present a set of images for helping NPR practitioners evaluate their image-based portrait stylisation algorithms. Using a standard set both facilitates comparisons with other methods and helps ensure that presented ...

    • Depth-aware Neural Style Transfer 

      Liu, Xiao-Chang; Cheng, Ming-Ming; Lai, Yu-Kun; Rosin, Paul L. (Association for Computing Machinery, Inc (ACM), 2017)
      Neural style transfer has recently received signi cant a ention and demonstrated amazing results. An e cient solution proposed by Johnson et al. trains feed-forward convolutional neural networks by de ning and optimizing ...

    • 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 ...

    • 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 ...

    • 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 ...

    • 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 ...

    • 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 ...

    • 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 ...

    • Shading with Painterly Filtered Layers: A Technique to Obtain Painterly Portrait Animations 

      Castaneda, Saif; Akleman, Ergun (Association for Computing Machinery, Inc (ACM), 2017)
      In this manuscript, we describe a process that can be used to create still and/or animated portrait paintings to be shown in Expressive Art Exhibit. Our process consists of two stages: (1) Creation of control textures for ...

    • Sketch and Shade : An interactive assistant for sketching and shading 

      Parakkat, Amal Dev; Joshi, Sarang Anil; Pundarikaksha, Uday Bondi; Muthuganapathy, Ramanathan (Association for Computing Machinery, Inc (ACM), 2017)
      We present a drawing assistant for sketching and for assisting users in shading a hand drawn sketch. The augmented reality based system uses a sketch made by a professional and uses it to help inexperienced users to do ...

    • Whole-Cloth Quilting Patterns from Photographs 

      Liu, Chenxi; Hodgins, Jessica; McCann, James (Association for Computing Machinery, Inc (ACM), 2017)
      Whole-cloth quilts are decorative and functional artifacts made of plain cloth embellished with complicated stitching patterns. We describe a method that can automatically create a sewing pattern for a whole-cloth quilt ...
