Stroke Correspondence Construction Using Manifold Learning
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Stroke correspondence construction is a precondition for generating inbetween frames from a set of key frames. In our case, each stroke in a key frame is a vector represented as a Disk B‐Spline Curve (DBSC) which is a ... -
Finding Syntactic Structures from Human Motion Data
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We present a new approach to motion rearrangement that preserves the syntactic structures of an input motion automatically by learning a context‐free grammar from the motion data. For grammatical analysis, we reduce an ... -
Non‐Linear Beam Tracing on a GPU
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Beam tracing combines the flexibility of ray tracing and the speed of polygon rasterization. However, beam tracing so far only handles linear transformations; thus, it is only applicable to linear effects such as planar ... -
Learning Boundary Edges for 3D‐Mesh Segmentation
(The Eurographics Association and Blackwell Publishing Ltd., 2011)This paper presents a 3D‐mesh segmentation algorithm based on a learning approach. A large database of manually segmented 3D‐meshes is used to learn a boundary edge function. The function is learned using a classifier which ... -
Simplex and Diamond Hierarchies: Models and Applications
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Hierarchical spatial decompositions are a basic modelling tool in a variety of application domains. Several papers on this subject deal with hierarchical simplicial decompositions generated through regular simplex bisection. ... -

Efficient Opacity Specification Based on Feature Visibilities in Direct Volume Rendering
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Due to 3D occlusion, the specification of proper opacities in direct volume rendering is a time-consuming and unintuitive process. The visibility histograms introduced by Correa and Ma reflect the effect of occlusion by ... -
Intelligent GPGPU Classification in Volume Visualization: A framework based on Error-Correcting Output Codes
(The Eurographics Association and Blackwell Publishing Ltd., 2011)In volume visualization, the definition of the regions of interest is inherently an iterative trial-and-error process finding out the best parameters to classify and render the final image. Generally, the user requires a ... -
Computing 3D Shape Guarding and Star Decomposition
(The Eurographics Association and Blackwell Publishing Ltd., 2011)This paper proposes an effective framework to compute the visibility guarding and star decomposition of 3D solid shapes. We propose a progressive integer linear programming algorithm to solve the guarding points that can ... -
Heat Walk: Robust Salient Segmentation of Non-rigid Shapes
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Segmenting three dimensional objects using properties of heat diffusion on meshes aim to produce salient results. The few existing algorithms based on heat diffusion do not use the full knowledge that can be gained from ... -
Optimized Topological Surgery for Unfolding 3D Meshes
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Constructing a 3D papercraft model from its unfolding has been fun for both children and adults since we can reproduce virtual 3D models in the real world. However, facilitating the papercraft construction process is still ... -
A Single Image Representation Model for Efficient Stereoscopic Image Creation
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Computer graphics is one of the most efficient ways to create a stereoscopic image. The process of stereoscopic CG generation is, however, still very inefficient compared to that of monoscopic CG generation. Despite that ... -
RepSnapping: Efficient Image Cutout for Repeated Scene Elements
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Repeated scene elements are copious and ubiquitous in natural images. Cutout of those repeated elements usually involves tedious and laborious user interaction by previous image segmentation methods. In this paper, we ... -
Video Brush: A Novel Interface for Efficient Video Cutout
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We present Video Brush, a novel interface for interactive video cutout. Inspired by the progressive selection scheme in images, our interface is designed to select video objects by painting on successive frames as the video ... -
Real Time Edit Propagation by Efficient Sampling
(The Eurographics Association and Blackwell Publishing Ltd., 2011)It is popular to edit the appearance of images using strokes, owing to their ease of use and convenience of conveying the user's intention. However, propagating the user inputs to the rest of the images requires solving ... -
River Networks for Instant Procedural Planets
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Realistic terrain models are required in many applications, especially in computer games. Commonly, procedural models are applied to generate the corresponding models and let users experience a wide variety of new environments. ... -
Authoring Hierarchical Road Networks
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We present a procedural method for generating hierarchical road networks connecting cities, towns and villages over large terrains. Our approach relies on an original geometric graph generation algorithm based on a non- ... -
Discriminative Sketch-based 3D Model Retrieval via Robust Shape Matching
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We propose a sketch-based 3D shape retrieval system that is substantially more discriminative and robust than existing systems, especially for complex models. The power of our system comes from a combination of a contourbased ... -
Bipartite Polar Classification for Surface Reconstruction
(The Eurographics Association and Blackwell Publishing Ltd., 2011)In this paper, we propose bipartite polar classification to augment an input unorganized point set P with two disjoint groups of points distributed around the ambient space of P to assist the task of surface reconstruction. ... -
SSD: Smooth Signed Distance Surface Reconstruction
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We introduce a new variational formulation for the problem of reconstructing a watertight surface defined by an implicit equation, from a finite set of oriented points; a problem which has attracted a lot of attention for ...
