      Jeschke, Stefan (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      This paper generalizes the well-known Diffusion Curves Images (DCI), which are composed of a set of Bezier curves with colors specified on either side. These colors are diffused as Laplace functions over the image domain, ...

    • Interactive Videos: Plausible Video Editing using Sparse Structure Points 

      Chang, Chia-Sheng; Chu, Hung-Kuo; Mitra, Niloy J. (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Video remains the method of choice for capturing temporal events. However, without access to the underlying 3D scene models, it remains difficult to make object level edits in a single video or across multiple videos. While ...
    • Seamless Video Stitching from Hand-held Camera Inputs 

      Lin, Kaimo; Liu, Shuaicheng; Cheong, Loong-Fah; Zeng, Bing (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Images/videos captured by portable devices (e.g., cellphones, DV cameras) often have limited fields of view. Image stitching, also referred to as mosaics or panorama, can produce a wide angle image by compositing several ...
    • Adapting Feature Curve Networks to a Prescribed Scale 

      Gehre, Anne; Lim, Isaak; Kobbelt, Leif (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Feature curves on surface meshes are usually defined solely based on local shape properties such as dihedral angles and principal curvatures. From the application perspective, however, the meaningfulness of a network of ...
    • Automatic Portrait Segmentation for Image Stylization 

      Shen, Xiaoyong; Hertzmann, Aaron; Jia, Jiaya; Paris, Sylvain; Price, Brian; Shechtman, Eli; Sachs, Ian (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Portraiture is a major art form in both photography and painting. In most instances, artists seek to make the subject stand out from its surrounding, for instance, by making it brighter or sharper. In the digital world, ...
    • SMARTCANVAS: Context-inferred Interpretation of Sketches for Preparatory Design Studies 

      Zheng, Youyi; Liu, Han; Dorsey, Julie; Mitra, Niloy J. (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      In early or preparatory design stages, an architect or designer sketches out rough ideas, not only about the object or structure being considered, but its relation to its spatial context. This is an iterative process, where ...
    • Animation Setup Transfer for 3D Characters 

      Avril, Quentin; Ghafourzadeh, Donya; Ramachandran, Srinivasan; Fallahdoust, Sahel; Ribet, Sarah; Dionne, Olivier; Lasa, Martin de; Paquette, Eric (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We present a general method for transferring skeletons and skinning weights between characters with distinct mesh topologies. Our pipeline takes as inputs a source character rig (consisting of a mesh, a transformation ...
    • Modeling and Estimation of Energy-Based Hyperelastic Objects 

      Miguel, Eder; Miraut, David; Otaduy, Miguel A. (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      In this paper, we present a method to model hyperelasticity that is well suited for representing the nonlinearity of real-world objects, as well as for estimating it from deformation examples. Previous approaches suffer ...
    • Learning 3D Deformation of Animals from 2D Images 

      Kanazawa, Angjoo; Kovalsky, Shahar; Basri, Ronen; Jacobs, David (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Understanding how an animal can deform and articulate is essential for a realistic modification of its 3D model. In this paper, we show that such information can be learned from user-clicked 2D images and a template 3D ...
    • Generalized As-Similar-As-Possible Warping with Applications in Digital Photography 

      Chen, Renjie; Gotsman, Craig (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Discrete conformal mappings of planar triangle meshes, also known as the As-Similar-As-Possible (ASAP) mapping, involve the minimization of a quadratic energy function, thus are very easy to generate and are popular in ...
    • Stylized Caustics: Progressive Rendering of Animated Caustics 

      Günther, Tobias; Rohmer, Kai; Rössl, Christian; Grosch, Thorsten; Theisel, Holger (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      In recent years, much work was devoted to the design of light editing methods such as relighting and light path editing. So far, little work addressed the target-based manipulation and animation of caustics, for instance ...
    • Improved Surface Quality in 3D Printing by Optimizing the Printing Direction
