Neatening sketched strokes using piecewise French Curves
(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 ... -
Combining Corners from Multiple Segmenters
(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 ... -
Now or Later: An Initial Exploration into User Perception ofMathematical Expression Recognition Feedback
(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 ... -
Single-View Sketch Based Modeling
(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 ... -
ClassySeg: A Machine Learning Approach to AutomaticStroke Segmentation
(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 ... -
Continuous Recognition and Visualization of Pen Strokes and Touch-Screen Gestures
(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 ... -
How to make a Quick$: Using Hierarchical Clustering toImprove the Efficiency of the Dollar Recognizer
(The Eurographics Association, 2011)We present Quick$ (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 ... -
Gesture-based design of 2D contours: an alternative tosketching?
(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 ... -
A Sketch-Based System for Highway Design
(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 ... -
Defining Precise Measurements with Sketched Annotations
(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 ... -
Sketch-Based Modeling of Smooth Surfaces Using AdaptiveCurve Networks
(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 ... -
Sketch Express: Facial Expressions Made Easy
(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 ... -
StereoBrush: Interactive 2D to 3D Conversion UsingDiscontinuous Warps
(The Eurographics Association, 2011)We introduce a novel workflow for stereoscopic 2D to 3D conversion in which the user “paints” depth onto a 2D image via sparse scribbles, instantaneously receiving intuitive 3D feedback. This workflow is enabled by the ... -
Reconstructing surfaces from sketched 3D irregular curvenetworks
(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 ... -
3D Modeling with a Symmetric Sketch
(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 ... -
Immersion and Embedding of Self-Crossing Loops
(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 ... -
Combining bimanual manipulation and pen-based inputfor 3D modelling
(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 ... -
Is the iPad useful for sketch input? A comparison with the Tablet PC
(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 ...
