Interactive Simulation of the Human Eye Depth of Field and Its Correction by Spectacle Lenses
(The Eurographics Association and Blackwell Publishing Ltd, 2007)This paper describes a fast rendering algorithm for verification of spectacle lens design. Our method simulates refraction corrections of astigmatism as well as myopia or presbyopia. Refraction and defocus are the main ... -
Contrast Restoration by Adaptive Countershading
(The Eurographics Association and Blackwell Publishing Ltd, 2007)The ABSTRACT is to be in fully-justified italicized text, between two horizontal lines, in one-column format, below the author and affiliation information. Use the word Abstract as the title, in 9-point Times, boldface ... -
Image Dequantization: Restoration of Quantized Colors
(The Eurographics Association and Blackwell Publishing Ltd, 2007)Color quantization replaces the color of each pixel with the closest representative color, and thus it makes the resulting image partitioned into uniformly-colored regions. As a consequence, continuous, detailed variations ... -
Style Transfer Functions for Illustrative Volume Rendering
(The Eurographics Association and Blackwell Publishing Ltd, 2007)Illustrative volume visualization frequently employs non-photorealistic rendering techniques to enhance important features or to suppress unwanted details. However, it is difficult to integrate multiple non-photorealistic ... -
Context-Aware Skeletal Shape Deformation
(The Eurographics Association and Blackwell Publishing Ltd, 2007)We describe a system for the animation of a skeleton-controlled articulated object that preserves the fine geometric details of the object skin and conforms to the characteristic shapes of the object specified through a ... -
Variational 3D Shape Segmentation for Bounding Volume Computation
(The Eurographics Association and Blackwell Publishing Ltd, 2007)We propose a variational approach to computing an optimal segmentation of a 3D shape for computing a union of tight bounding volumes. Based on an affine invariant measure of e-tightness, the resemblance to ellipsoid, a ... -
Boundary Constrained Swept Surfaces for Modelling and Animation
(The Eurographics Association and Blackwell Publishing Ltd, 2007)Due to their simplicity and intuitiveness, swept surfaces are widely used in many surface modelling applications. In this paper, we present a versatile swept surface technique called the boundary constrained swept surfaces. ... -
Prediction of Individual Non-Linear Aging Trajectories of Faces
(The Eurographics Association and Blackwell Publishing Ltd, 2007)Represented in a Morphable Model, 3D faces follow curved trajectories in face space as they age. We present a novel algorithm that computes the individual aging trajectories for given faces, based on a non-linear function ... -
Volume Preservation of Multiresolution Meshes
(The Eurographics Association and Blackwell Publishing Ltd, 2007)Geometric constraints have proved to be efficient for enhancing the realism of shape animation. The present paper addresses the computation and the preservation of the volume enclosed by multiresolution meshes. A wavelet ... -
3D Lip-Synch Generation with Data-Faithful Machine Learning
(The Eurographics Association and Blackwell Publishing Ltd, 2007)This paper proposes a new technique for generating three-dimensional speech animation. The proposed technique takes advantage of both data-driven and machine learning approaches. It seeks to utilize the most relevant part ... -
Head-eye Animation Corresponding to a Conversation for CG Characters
(The Eurographics Association and Blackwell Publishing Ltd, 2007)CG character animations, in which CG characters engage in conversations, are widely used in multimedia contents such as videos and games. In constructing such an animation, we should consider about many factors, such as ... -
On-the-fly Curve-skeleton Computation for 3D Shapes
(The Eurographics Association and Blackwell Publishing Ltd, 2007)The curve-skeleton of a 3D object is an abstract geometrical and topological representation of its 3D shape. It maps the spatial relation of geometrically meaningful parts to a graph structure. Each arc of this graph ... -
What can Computer Graphics expect from 3D Computer Vision?
(The Eurographics Association and Blackwell Publishing Ltd, 2007)Computer Vision is a discipline whose ultimate goal is to interpret optical images of real scenes. It is well understood that such a problem is cursed by ambiguity of interpretation and uncertainty of evidence. Despite ...
