Fields of Experts for Image-based Rendering [PDF]

Procedings of the British Machine Vision Conference 2006, 2006
Image priors for novel view synthesis have traditionally been non-parametric models based on large libraries of image patch exemplars, producing highquality results but making inference very slow. Recently a parametric framework, called Fields of Experts, has been proposed for image restoration that promises to speed up inference dramatically.

High-Resolution Hologram Calculation Method Based on Light Field Image Rendering

Applied Sciences, 2020
A fast calculation method for a full parallax high-resolution hologram is proposed based on elemental light field image (EI) rendering. A 3D object located near the holographic plane is firstly rendered as multiple EIs with a pinhole array.

A progressive refinement approach for the visualisation of implicit surfaces [PDF]

, 2007
Visualising implicit surfaces with the ray casting method is a slow procedure. The design cycle of a new implicit surface is, therefore, fraught with long latency times as a user must wait for the surface to be rendered before being able to decide what ...

A Real-Time Super Multiview Rendering Pipeline for Wide Viewing-Angle and High-Resolution 3D Displays Based on a Hybrid Rendering Technique

IEEE Access, 2020
Super multiview (SMV) 3D displays with a directional diffuser can provide dense viewpoints, wide viewing angles and high image quality. However, traditional SMV 3D rendering pipelines have many disadvantages, such as high time costs, low image quality ...

Performance Optimization Technique for Large-Scale Parallel Volume Rendering Based on Multiple Rendering Pipelines [PDF]

Jisuanji gongcheng
For large-scale scientific data output in numerical simulations, volume rendering methods inevitably perform high-density ray sampling to capture complex physical features, resulting in significant computational overhead and data increment.

Photometric image-based rendering for virtual lighting image synthesis [PDF]

, 1999
A concept named Photometric Image-Based Rendering (PIBR) is introduced for a seamless augmented reality. The PIBR is defined as image-based rendering which covers appearance changes caused by the lighting condition changes, while Geometric Image-Based ...

Reflection space image based rendering [PDF]

Proceedings of the 26th annual conference on Computer graphics and interactive techniques - SIGGRAPH '99, 1999
High quality, physically accurate rendering at interactive rates haswidespread application, but is a daunting task. We attempt to bridgethe gap between high-quality offline and interactive rendering byusing existing environment mapping hardware in combination witha novel Image Based Rendering (IBR) algorithm. The primary contribution lies in performing

VISUALISATION OF COMPLEX 3D CITY MODELS ON MOBILE WEBBROWSERS USING CLOUD-BASED IMAGE PROVISIONING [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015
Rendering large city models with high polygon count and a vast amount of textures at interactive frame rates is a rather difficult to impossible task as it highly depends on the client hardware, which is often insufficient, even if out-of-core rendering ...

View synthesis with sparse light field for 6DoF immersive video

ETRI Journal, 2022
Virtual view synthesis, which generates novel views similar to the characteristics of actually acquired images, is an essential technical component for delivering an immersive video with realistic binocular disparity and smooth motion parallax.
