Enforcing Scene Constraints in Single View Reconstruction
(The Eurographics Association, 2007)Three-dimensional reconstruction from a single view is an under-constrained process that relies critically upon the availability of prior knowledge about the imaged scene. This knowledge is assumed to be supplied by a user ... -
Volumetric Normal Mapping in Rendering of Multivariate Volume Data
(The Eurographics Association, 2007)The work presented in this paper introduces volumetric normal maps for producing visual structure in direct volume rendering (DVR) of 3D data for the purpose of visualizing multiple attributes in a 3D volume. We use ... -
High Speed Skin Color Detection and Localization on a GPU
(The Eurographics Association, 2007)In this paper, we present a simple yet novel method for high speed skin color detection and localization on images and video using the Graphics Processing Unit (GPU) and common graphics programming techniques. Our approach ... -
Improved Skeleton Computation of an Encoded Volume
(The Eurographics Association, 2007)In this communication, we present an improvement of an existing thinning algorithm that computes a surface skeleton from a binary volume. The method makes an intensive use of Boolean operations and works on a special ... -
Exemplar-based Worn Edges
(The Eurographics Association, 2007)To counteract the sterile look of computer-generated worlds, we introduce a procedural model for worn edges that can be seen in buildings and stones: edges that have suffered minor damage at multiple points, resulting in ... -
Stabilized Noise
(The Eurographics Association, 2007)Perlin noise is generated by interpolation of a pre-defined random number table. However since the random number table is generated without considering the ideal properties of noise for computer graphics, the resulting ... -
Exact Computation of the Hausdorff Distance between Triangular Meshes
(The Eurographics Association, 2007)We present an algorithm that computes the exact Hausdorff distance between two arbitrary triangular meshes. Our method computes squared distances for each point on each triangle of one mesh to all relevant triangles of the ... -
View-based Shape Similarity using Mutual Information Spheres
(The Eurographics Association, 2007)We present a new method for computing the shape similarity between 3D polygonal models using an informationtheoretic viewpoint selection framework. Given a 3D model, a sphere of viewpoints surrounding this model is used ... -
Shape Analysis for Augmented Topological Shape Descriptor
(The Eurographics Association, 2007)In this work we propose a scheme for analysis of the shape of a 3D model.We use Extended Reeb Graph to describe the topological structure of the model which we further enrich with extracted geometrical features. The nodes ... -
Reeb Chart Unfolding Based 3D Shape Signatures
(The Eurographics Association, 2007)This paper presents a novel surface parameterization based technique that addresses the pose insensitive shape signature problem for surface models of arbitrary genus. It is based on the key idea that two surface models ... -
An Accurate Implicit Field Representation for Meshes and Its Adapted Triangulation Algorithms
(The Eurographics Association, 2007)The classic implicit scalar field distance transform representation of a mesh is very useful to perform many mesh processing operations and to obtain better results than with other methods. In this paper we propose a new ... -
A Unified Interpolatory and Approximation sqrt-3 Subdivision Scheme
(The Eurographics Association, 2007)We have found that there is a relationship between the cubic B-spline and four-point curve subdivision method. In the paper it is used to deduce interpolatory subdivision schemes from cubic B-spline based approximation ...
