Visual Languages and Visual Thinking: Sketch Based Interaction and Modeling
(The Eurographics Association, 2009)
Research on sketching with computers dates to the earliest days of modern computing. Recent work in this area, combined with other advances in hardware and software technologies promises, finally, significant impact. The ...
Sketch-Based Subdivision Models
(The Eurographics Association, 2009)
Designing a control mesh (or a polyhedron) for a subdivision model is a tedious task. It involves many difficult decisions such as how to minimize the number of extraordinary vertices, how best to choose their valencies, ...
Automatic Evaluation of Sketch Recognizers
(The Eurographics Association, 2009)
We present our toolkit to automatically evaluate recognition algorithms. There are few published comparative evaluations of sketch recognition algorithms and those that exist do not provide benchmarking or direct comparisons ...
Modeling from Contour Drawings
(The Eurographics Association, 2009)
Occlusion contours are a natural feature to draw when tracing an object in an image or when drawing an object. We investigate the development of 3D models from multi-stroke contour drawings with the help of a 3D template ...
A Usability Evaluation of AlgoSketch: A Pen-Based Application for Mathematics
(The Eurographics Association, 2009)
AlgoSketch is a pen-based system for entering and editing mathematics. It supports interactive computation and early-stage mathematical algorithm design. In its paper-like environment, mathematical expressions can be en- ...
On Expert Performance in 3D Curve-Drawing Tasks
(The Eurographics Association, 2009)
A study is described which examines the drawing accuracy of experts when drawing foreshortened projections of 3D curves in ecologically-valid conditions. The main result of this study is that the distribution of error in ...
A Sketch-based Interface for Photo Pop-up
(The Eurographics Association, 2009)
We present sketch-based tools for single-view modeling which allow for quick 3D mark-up of a photograph. With our interface, detailed 3D models can be produced quickly and easily. After establishing the background geometry, ...
Towards Beautification of Freehand Sketches using Suggestions
(The Eurographics Association, 2009)
Beautification of freehand sketches is integral for building robust sketch understanding systems and sketch-based inter-faces for CAD. Many of the current methods for beautification do not consider some important information ...
The Effect of Task on Classification Accuracy: Using Gesture Recognition Techniques in Free-Sketch Recognition
(The Eurographics Association, 2009)
Generating, grouping, and labeling free-sketch data is a difficult and time-consuming task for both user study participants and researchers. To simplify this process for both parties, we would like to have users draw ...
A descriptor for large scale image retrieval based on sketched feature lines
(The Eurographics Association, 2009)
We address the problem of large scale sketch based image retrieval, searching in a database of over a million images. The search is based on a descriptor that elegantly addresses the asymmetry between the binary user sketch ...
