Efficient image-based rendering
2023Jüngste Fortschritte im Bereich Echtzeit-Raytracing und Deep Learning haben den Realismus computergenerierter Bilder erheblich verbessert. Konventionelle 3DComputergrafik (CG) kann jedoch nach wie vor zeit- und ressourcenintensiv sein, insbesondere bei der Erstellung fotorealistischer Simulationen von komplexen oder animierten Szenen.

Image-based streamline generation and rendering
IEEE Transactions on Visualization and Computer Graphics, 2007Seeding streamlines in 3D flow fields without considering their projections in screen space can produce visually cluttered rendering results. Streamlines will overlap or intersect with each other in the output image, which makes it difficult for the user to perceive the underlying flow structure.

Image-based rendering in the gradient domain
ACM Transactions on Graphics, 2013We propose a novel image-based rendering algorithm for handling complex scenes that may include reflective surfaces. Our key contribution lies in treating the problem in the gradient domain. We use a standard technique to estimate scene depth, but assign depths to image gradients rather than pixels.

Abstract Image-based rendering (IBR) is a process of synthesizing images at novel viewpoints based on a set of existing images. Although it is primarily a task in computer graphics for novel view synthesis, it can be treated as a signal processing problem: How do we perform sampling, representation, and reconstruction for a high-dimensional function?

Hybrid Geometric - Image Based Rendering
Computer Graphics Forum, 2002We present a Hybrid Geometric-Image Based Rendering (HGIBR) system for displaying very complex geometrical models at interactive frame rates. Our approach replaces distant geometry with a combination of image-based representations and geometry, while rendering nearby objects from geometry.

Error-Concealed Image-based Rendering [PDF]
, 2011 Fotorealismus ist seit jeher eines der großen Ziele in der Computergrafik. Anstatt die Komplexität der Natur mit standardisierten Modellierungswerkzeugen nachzubauen, gehen bildbasierte Ansätze den umgekehrten Weg und verwenden reale Bildaufnahmen zur Modellierung, da diese bereits per Definition fotorealistisch sind.

Image‐based embroidery modeling and rendering
Computer Animation and Virtual Worlds, 2016AbstractEmbroidery is a traditional handicraft of sewing stitches into fabric or other materials in different patterns, and this ancient non‐photorealistic art form has not drawn enough attention thus far. In this paper, we present an image‐based method to simulate the traditional embroidery art.

Simplistic dynamic image based rendering
Proceedings of the 1st international conference on Computer graphics and interactive techniques in Austalasia and South East Asia - GRAPHITE '03, 2003We present a very inexpensive way of creating dynamic image-based renderings of digitally recorded, photo realistic, real-life objects. Together with computer vision algorithms, the recorded person is visualized using the Relief Texture Mapping algorithm [Oliveira et al. 2000].

RAYSET: A TAXONOMY FOR IMAGE-BASED RENDERING
International Journal of Image and Graphics, 2006A new concept, referred to as rayset, is discussed in this paper. It is a parametric function consisting of two mapping relations. The first one maps from a parameter space to the ray space, while the second one maps from the parameter space to the attribute space.

Image-based rendering and tracking of faces
IEEE International Conference on Image Processing 2005, 2005In this paper, we present an image-based method for the tracking and rendering of faces. We use the algorithm in an immersive video conferencing system where multiple participants are placed at a virtual table. This requires viewpoint modification of dynamic objects.
