Antialiasing for Automultiscopic 3D Displays
(The Eurographics Association, 2006)Automultiscopic displays show stereoscopic images that can be viewed from any viewpoint without special glasses. They hold great promise for the future of television and digital entertainment. However, the image quality ... -
Appearance based object modeling using texture database: Acquisition, compression and rendering
(The Eurographics Association, 2002)Image-based object modeling can be used to compose photorealistic images of modeled objects for various rendering conditions, such as viewpoint, light directions, etc. However, it is challenging to acquire the large number ... -
Approximate Soft Shadows on Arbitrary Surfaces using PenumbraWedges
(The Eurographics Association, 2002)Shadow generation has been subject to serious investigation in computer graphics, and many clever algorithms have been suggested. However, previous algorithms cannot render high quality soft shadows onto arbitrary, animated ... -
Approximating the Location of Integrand Discontinuities for Penumbral Illumination with Area Light Sources
(The Eurographics Association, 1999)The problem of computing soft shadows with area light sources has received considerable attention in computer graphics. In part, this is a difficult problem because the integral that defines the radiance at a point must ... -
Ardeco: Automatic Region DEtection and COnversion
(The Eurographics Association, 2006)We present Ardeco, a new algorithm for image abstraction and conversion from bitmap images into vector graphics. Given a bitmap image, our algorithm automatically computes the set of vector primitives and gradients that ... -
An Area-Preserving Parametrization for Spherical Rectangles
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We present an area-preserving parametrization for spherical rectangles which is an analytical function with domain in the unit rectangle [0;1]2 and range in a region included in the unit-radius sphere. The parametrization ... -
Artistic Composition for Image Creation
(The Eurographics Association, 2001)Altering the viewing parameters of a 3D object results in computer graphics images of varying quality. One aspect of image quality is the composition of the image. While the esthetic properties of an image are subjective, ... -
Artistic Illumination Transfer for Portraits
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Relighting a portrait in a single image is still a challenging problem, particularly when only a single artistic reference photograph or painting is provided. In this paper, we propose an artistic illumination transfer ... -
Automatic Cinemagraph Portraits
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Cinemagraphs are a popular new type of visual media that lie in-between photos and video; some parts of the frame are animated and loop seamlessly, while other parts of the frame remain completely still. Cinemagraphs are ... -
Automatic Multiperspective Images
(The Eurographics Association, 2006)Multiperspective images generated from a collection of photographs or a videostream can be used to effectively summarize long, roughly planar scenes such as city streets. The final image will span a larger field of view ... -
AutoStyle: Automatic Style Transfer from Image Collections to Users' Images
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Stylizing photos, to give them an antique or artistic look, has become popular in recent years. The available stylization filters, however, are usually created manually by artists, resulting in a narrow set of choices. ... -
Bayesian Relighting
(The Eurographics Association, 2005)We present a simple method for relighting real objects viewed from a fixed camera position. Instead of setting up a calibrated measurement device, such as a light stage, we manually sweep a spotlight over the walls of a ... -
BendyLights: Artistic Control of Direct Illumination by Curving Light Rays
(The Eurographics Association and Blackwell Publishing Ltd, 2010)In computer cinematography, artists routinely use non-physical lighting models to achieve desired appearances. This paper presents BendyLights, a non-physical lighting model where light travels nonlinearly along splines, ... -
Beyond Photorealism
(The Eurographics Association, 1999)For around 30 years the computer graphics research community has pursued photorealism as though it were the ultimate form of visual expression. Yet, as an art form, photorealism is one of many abstrations that an artist ... -
Bidirectional Importance Sampling for Direct Illumination
(The Eurographics Association, 2005)Image-based representations for illumination can capture complex real-world lighting that is difficult to represent in other forms. Current importance sampling strategies for image-based illumination have difficulties in ... -
Bidirectional Instant Radiosity
(The Eurographics Association, 2006)This paper presents a new sampling strategy to achieve interactive global illumination on one commodity computer. The goal is to propose an efficient numerical stochastic scheme which can be well adapted to a fast rendering ... -
Bilinear Accelerated Filter Approximation
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Our method approximates exact texture filtering for arbitrary scales and translations of an image while taking into account the performance characteristics of modern GPUs. Our algorithm is fast because it accesses textures ... -
Bixels: Picture Samples with Sharp Embedded Boundaries
(The Eurographics Association, 2004)Pixels store a digital image as a grid of point samples that can reconstruct a limited-bandwidth continuous 2-D source image. Although convenient for anti-aliased display, these bandwidth limits irreversibly discard important ... -
BTF Compression via Sparse Tensor Decomposition
(The Eurographics Association and Blackwell Publishing Ltd, 2009)In this paper, we present a novel compression technique for Bidirectional Texture Functions based on a sparse tensor decomposition. We apply the K-SVD algorithm along two different modes of a tensor to decompose it into a ... -
C-LOD: Context-aware Material Level-of-Detail applied to Mobile Graphics
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Attention-based Level-Of-Detail (LOD) managers downgrade the quality of areas that are expected to go unnoticed by an observer to economize on computational resources. The perceptibility of lowered visual fidelity is ...
