Fast Shadow Removal Using Adaptive Multi‐Scale Illumination Transfer
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
In this paper, we present a new method for removing shadows from images. First, shadows are detected by interactive brushing assisted with a Gaussian Mixture Model. Secondly, the detected shadows are removed using an ...
SCALe-invariant Integral Surfaces
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Extraction of skeletons from solid shapes has attracted quite a lot of attention, but less attention was paid so far to the reverse operation: generating smooth surfaces from skeletons and local radius information. Convolution ...
Sketch-to-Design: Context-Based Part Assembly
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Designing 3D objects from scratch is difficult, especially when the user intent is fuzzy and lacks a clear target form. We facilitate design by providing reference and inspiration from existing model contexts. We rethink ...
Adaptive Ray-bundle Tracing with Memory Usage Prediction: Efficient Global Illumination in Large Scenes
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
This paper proposes an adaptive rendering technique for ray-bundle tracing. Ray-bundle tracing can be done by per-pixel linked-list construction on a GPU rasterization pipeline. This rasterization based approach offers ...
A Survey of Real-Time Hard Shadow Mapping Methods
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Because of its versatility, speed and robustness, shadow mapping has always been a popular algorithm for fast hard shadow generation since its introduction in 1978, first for offline film productions and later increasingly ...
Design and Fabrication of Faceted Mirror Arrays for Light Field Capture
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
The high resolution of digital cameras has made single‐shot, single‐sensor acquisition of light fields feasible, though considerable design effort is still necessary in order to construct the necessary collection of optical ...
Efficient Interpolation of Articulated Shapes Using Mixed Shape Spaces
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Interpolation between compatible triangle meshes that represent different poses of some object is a fundamental operation in geometry processing. A common approach is to consider the static input shapes as points in a ...
A Progressive Tri-level Segmentation Approach for Topology-Change-Aware Video Matting
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Previous video matting approaches mostly adopt the ''binary segmentation + matting'' strategy, i.e., first segment each frame into foreground and background regions, then extract the fine details of the foreground boundary ...
Hermite Radial Basis Functions Implicits
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
The Hermite radial basis functions (HRBF) implicits reconstruct an implicit function which interpolates or approximates scattered multivariate Hermite data (i.e. unstructured points and their corresponding normals). ...
Using VisTrails and Provenance for Teaching Scientific Visualization
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Over the last 20 years, visualization courses have been developed and offered at universities around the world. Many of these courses use established visualization libraries and tools (e.g. VTK, ParaView, AVS, VisIt) as a ...
