Quadratic Encoding for Hand Pose Reconstruction from Multi-Touch Input
(The Eurographics Association, 2015)
One of the most compelling challenges in virtual reality today is to allow users to carry out virtual manipulation tasks using their hands. Multi-touch devices are an interesting interface for this task, as they are widely ...
Sketch-Based Controllers for Blendshape Facial Animation
(The Eurographics Association, 2015)
The blendshape approach is a widely used technique to generate realistic facial animation. However, creating blendshape facial animations using traditional weight editing tools requires either memorizing the function of a ...
GHand: A GPU Algorithm for Realtime Hand Pose Estimation Using Depth Camera
(The Eurographics Association, 2015)
We present GHand, a GPU algorithm for markerless hand pose estimation from a single depth image obtained from a commodity depth camera. Our method uses a dual random forest approach: the first forest estimates position and ...
Woodification: User-Controlled Cambial Growth Modeling
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
We present a botanical simulation of secondary (cambial) tree growth coupled to a physical cracking simulation of its bark. Whereas level set growth would use a fixed resolution voxel grid, our system extends the deformable ...
IsoMatch: Creating Informative Grid Layouts
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Collections of objects such as images are often presented visually in a grid because it is a compact representation that lends itself well for search and exploration. Most grid layouts are sorted using very basic criteria, ...
Approximating the Generalized Voronoi Diagram of Closely Spaced Objects
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
We present an algorithm to compute an approximation of the generalized Voronoi diagram (GVD) on arbitrary collections of 2D or 3D geometric objects. In particular, we focus on datasets with closely spaced objects; GVD ...
Paint and Click: Unified Interactions for Image Boundaries
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Image boundaries are a fundamental component of many interactive digital photography techniques, enabling applications such as segmentation, panoramas, and seamless image composition. Interactions for image boundaries often ...
Light Chisel: 6DOF Pen Tracking
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
We present a novel interaction device tracked in 6 degrees of freedom by two commodity cameras. The inexpensive Light Chisel is statically illuminated with two LEDs, and uses no additional sensor (e.g. inertial or magnetic) ...
