    • 3D Modeling with a Symmetric Sketch 

      Öztireli, A. C.; Uyumaz, U.; Popa, T.; Sheffer, A.; Gross, M. (The Eurographics Association, 2011)
      We propose a method that allows geometric operations such as view change, deformation, simulation, or symmetrization on a single off-line sketch via a proxy geometry reconstructed directly from the sketch. The reconstruction ...
    • ClassySeg: A Machine Learning Approach to AutomaticStroke Segmentation 

      Herold, J.; Stahovich, T. F. (The Eurographics Association, 2011)
      We present ClassySeg, a technique for segmenting hand-drawn pen strokes into lines and arcs. ClassySeg employs machine learning techniques to infer the segmentation intended by the drawer. The technique begins by identifying ...
    • Combining bimanual manipulation and pen-based inputfor 3D modelling 

      Lopes, Pedro; Mendes, Daniel; Araújo, Bruno; Jorge, Joaquim A. (The Eurographics Association, 2011)
      Multitouch enabled surfaces can bring advantages to modelling scenarios, in particular if bimanual and pen input can be combined. In this work, we assess the suitability of multitouch interfaces to 3D sketching tasks. We ...
    • Combining Corners from Multiple Segmenters 

      Wolin, Aaron; Field, Martin; Hammond, Tracy (The Eurographics Association, 2011)
      Pen-based interfaces utilize sketch recognition in order to allow users to sketch complex systems with intuitive input. In order to allow users to freely draw their ideas without constraints, the low-level techniques ...
    • Continuous Recognition and Visualization of Pen Strokes and Touch-Screen Gestures 

      Kristensson, P.O.; Denby, L.C. (The Eurographics Association, 2011)
      We present a technique that enables continuous recognition and visualization of pen strokes and touch-screen gestures. We describe an incremental recognition algorithm that provides probability distributions over template ...
    • Defining Precise Measurements with Sketched Annotations 

      Kebodeaux, Kourtney; Field, Martin; Hammond, Tracy (The Eurographics Association, 2011)
      Technology has been largely employed in the modern education system but rarely fosters natural communication between the human and the machine. We wish to explore the use of sketch recognition based software as a medium ...
    • Gesture-based design of 2D contours: an alternative tosketching? 

      Delamé, T.; Léon, J.C.; Cani, M.P.; Blanch, R. (The Eurographics Association, 2011)
      In addition to being a very expressive media, 2D sketches representing the contour of a shape are commonly used as a basis for 3D sketch-based modeling. This paper investigates an alternative to the standard way of creating ...
    • How to make a Quick$: Using Hierarchical Clustering toImprove the Efficiency of the Dollar Recognizer 

      Reaver, J.; Stahovich, T. F.; Herold, J. (The Eurographics Association, 2011)
      We present Quick$ (QuickBuck), an extension to the Dollar Recognizer designed to improve recognition efficiency. While the Dollar Recognizer must search all training templates to recognize an unknown symbol, Quick$ employs ...
    • Immersion and Embedding of Self-Crossing Loops 

      Mukherjee, Uddipan; M.Gopi,; Rossignac, Jarek (The Eurographics Association, 2011)
      The process of generating a 3D model from a set of 2D planar curves is complex due to the existence of many solutions. In this paper we consider a self-intersecting planar closed loop curve, and determine the 3D layered ...
    • Is the iPad useful for sketch input? A comparison with the Tablet PC 

      MacLean, S.; Tausky, D.; Labahn, G.; Lank, E.; Marzouk, M. (The Eurographics Association, 2011)
      Despite the increasing prevalence of touch-based tablet devices, little attention has been paid to what effects, if any, this form factor has on sketch behaviours in general and on sketch recognizers in particular.We ...
    • Neatening sketched strokes using piecewise French Curves 

      McCrae, James; Singh, Karan (The Eurographics Association, 2011)
      We apply traditional bimanual curve modeling using French curves to the problem of automatic neatening of sketched strokes. Given a sketched input stroke and a set of template French curves we present an approach that fits ...
    • Now or Later: An Initial Exploration into User Perception ofMathematical Expression Recognition Feedback 

      Bott, Jared N.; Gabriele, Daniel; Jr., Joseph J. LaViola (The Eurographics Association, 2011)
      Mathematical handwriting recognition is an important method of mathematics input for computers. While strides in recognition have been made in recent years, recognition is still at a level where mistakes are common and ...
    • Reconstructing surfaces from sketched 3D irregular curvenetworks 

      Morigi, S.; Rucci, M. (The Eurographics Association, 2011)
      This paper presents a system for designing free-form surfaces starting from a sketched 3D irregular curve network. By simply dragging a smart-pen device in space, the user draws and refines arbitrary 3D style-curves that ...
    • Single-View Sketch Based Modeling 

      Andre, Alexis; Saito, Suguru (The Eurographics Association, 2011)
      This paper presents a new sketch modeling system that is able to generate complex objects drawn from a unique viewpoint. The user draws the model in an iterative manner, adding simple parts to the existing object until ...
    • Sketch Express: Facial Expressions Made Easy 

      Miranda, José Carlos; Alvarez, Xenxo; Orvalho, João; Gutierrez, Diego; Sousa, A. Augusto; Orvalho, Verónica (The Eurographics Association, 2011)
      Finding an effective control interface to manipulate complex eometric objects has traditionally relied on experienced users to place the animation controls. This process, whether for key framed or for motion captured ...
    • Sketch-Based Modeling of Smooth Surfaces Using AdaptiveCurve Networks 

      Orbay, Günay; Kara, Levent Burak (The Eurographics Association, 2011)
      We present a new 3D surface modeling method that enables a rapid creation and modification of globally smooth surfaces from curve networks. The key feature of the proposed method is that it assumes the sketched curve ...
    • A Sketch-Based System for Highway Design 

      Applegate, C. S.; Laycock, S. D.; Day, A. M. (The Eurographics Association, 2011)
      To create traffic simulations of high visual-fidelity, each road needs to be designed and modelled in great detail to conform with the governing rules and regulations of highway design. Roads could be created manually, but ...
