    • Modeling-in-Context: User Design of Complementary Objects with a Single Photo 

      Lau, Manfred; Saul, Greg; Mitani, Jun; Igarashi, Takeo (The Eurographics Association, 2010)
      The products that we use everyday are typically designed and produced for mass consumption. However, it is difficult for such products to satisfy the needs of individual users. We present a framework that allows the end-user ...
    • Exploring Frame Gestures for Fluid Freehand Sketching 

      Nijboer, Menno; Gerl, Moritz; Isenberg, Tobias (The Eurographics Association, 2010)

    • A Sketching Interface for Sitting-Pose Design 

      Lin, Juncong; Igarashi, Takeo; Mitani, Jun; Saul, Greg (The Eurographics Association, 2010)
      We present a sketch interface for interactively placing a 3D human character in a sitting position on a chair. The user first sketches the target pose as a 2D stick figure. The user can specify whether a joint will be ...
    • Sketch-Based Recognition System for General Articulated Skeletal Figures 

      Zamora, Shane; Sherwood, Timothy (The Eurographics Association, 2010)
      We present a new recognition system for detecting general articulated skeletal figures in sketch-based applications. We abstract drawing style from recognition by defining figures using two data models: templates and figure ...
    • The Power of Automatic Feature Selection: Rubine on Steroids 

      Blagojevic, Rachel; Chang, Samuel Hsiao-Heng; Plimmer, Beryl (The Eurographics Association, 2010)
      Digital ink features drive recognition engines. Intuitively, we understand that particular features are of more value for some problems than others. Likewise, inclusion of poor features may be detrimental to recognition ...
    • Assisted Multitouch Image-Based Reconstruction 

      Bauer, Frank; Stamminger, Marc (The Eurographics Association, 2010)
      We present an image-based reconstruction approach for mobile, multitouch enabled devices. A novel scene description based on a multi-agent system is used to allow a real-time reconstruction workflow even on devices with ...
    • Computing Confidence Values for Geometric Constraints for use in Sketch Recognition 

      Johnston, Joshua; Hammond, Tracy (The Eurographics Association, 2010)
      Geometric constraints are used by many sketch recognition systems to perform high-level assembly of components of a sketch into semantic structures. However, with a few notable exceptions, most of the current recognition ...
    • Inkus: A Freehand Method of Creating Business Process Models 

      Mangano, Nicolas; Sukaviriya, Noi (The Eurographics Association, 2010)
      Business process modeling has become an industry wide practice for business transformation consulting. Tools that support business process modeling are designed for experienced users to draw a process with precision and ...
    • Shape Modeling with Sketched Feature Lines in Immersive 3D Environments 

      Perkunder, Helen; Israel, Johann Habakuk; Alexa, Marc (The Eurographics Association, 2010)
      In this paper we address the question whether automatic shape creation using sketched strokes as input in an immersive 3D environment supports the sketching process in early phases of product design. To investigate this ...
    • Sketching Variational Hermite-RBF Implicits 

      Brazil, Emilio Vital; Macedo, Ives; Sousa, Mario Costa; Figueiredo, Luiz Henrique de; Velho, Luiz (The Eurographics Association, 2010)
      We present techniques for modeling Variational Hermite Radial Basis Function (VHRBF) Implicits using a set of sketch-based interface and modeling (SBIM) operators. VHRBF Implicits is a simple and compact representation ...
    • Folding Avoidance in Skeletal Strokes 

      Asente, Paul J. (The Eurographics Association, 2010)
      Skeletal strokes is a method for mapping vector artwork defined along a straight path onto an arbitrary destination path. It is commonly used to give sketches a hand-drawn look, by mapping a scanned natural-medium stroke ...
    • Drawing with the Flow: A Sketch-Based Interface for Illustrative Visualization of 2D Vector Fields 

      Schroeder, David; Coffey, Dane; Keefe, Dan (The Eurographics Association, 2010)
      This paper presents Drawing with the Flow, a sketch-based interface for illustrating 2D vector fields. Drawing with the Flow explores the problem of making scientific visualization tools accessible to artists and illustrators, ...
    • Investigating the Learnability of Immersive Free-Hand Sketching 

      Wiese, Eva; Israel, Johann Habakuk; Meyer, Achim; Bongartz, Sara (The Eurographics Association, 2010)
      Immersive modeling systems which allow for sketching and constructing three-dimensional product models receive growing interest from both academic research and industry [DBWB*00; FASM02; IWMS09; KAMD*08; KAML*01]. The ...
    • Modeling 2.5D Plants from Ink Paintings 

      Amati, Cristina; Brostow, Gabriel J. (The Eurographics Association, 2010)
      Chinese ink painting, known as sumi-e, is a traditional art form based on careful placement of expressive brush strokes. To extend such brush strokes from their paper form, we propose a system that can digitize and transform ...
    • Stroke Extraction and Classification for Mesh Inflation 

      Olsen, Luke; Samavati, Faramarz F. (The Eurographics Association, 2010)
      We provide a method for extracting and classifying stroke segments from a line drawing or sketch with the goal of producing perceptually-valid output in the context of mesh inflation. This is important as processing freehand ...
