Color Transfer of 3D Point Clouds For XR Applications
In this paper, we analyse and compare four different color transfer algorithms, which were originally developed for 2D images, for 3D point clouds. In particular, we transfer the color distribution of a given reference 3D point cloud to a s...
The Perceptually-Supported and the Subjectively-Preferred Viewing Distance of Projection-Based Light Field Displays
As the research efforts and development processes behind light field visualization technologies advance, potential novel use cases emerge. These contexts of light field display utilization fundamentally depend on the distance of observation...
Depth Image-Based Rendering of Non-Lambertian Content in MPEG Immersive Video
In the context of the development of MPEG-I standard for immersive video compression ISO/IEC 23090-12 (MIV), the need of handling scenes with non-Lambertian materials arose. This class of material is omnipresent in natural scenes, but viola...
3D location estimation of light sources in room-scale scenes
In this paper we present our on-going work on light source estimation in room-scale scenes for more photorealistic experiences. Our unique input is an up-to-date textured 3D mesh of a real uncontrolled environment obtained using a consumer ...
Multiview from micro-lens image of multi-focused plenoptic camera
Multi-focused Plenoptic cameras (Plenoptic 2.0) allow the acquisition of the Light-Field of a scene. However, extracting a novel view from the resulting Micro-Lens Array (MLA) image poses several challenges: micro-lenses calibration, noise ...
Accurate human body reconstruction for volumetric video
In this work, we enhance a professional end-to-end volumetric video production pipeline to achieve high-fidelity human body reconstruction using only passive cameras. While current volumetric video approaches estimate depth maps using tradi...
Performance analysis of DIBR-based view synthesis with kinect azure
DIBR (Depth Image Based Rendering) can synthesize Free Navigation virtual views with sparse multiview texture images and corresponding depth maps. There are two ways to obtain depth maps: through software or depth sensors, which is a trade-...
From Photogrammetric Reconstruction to Immersive VR Environment
There are several steps to generate a VR environment from images: choose experimental conditions (scene, camera, trajectory, weather), take the images, reconstruct a textured 3D model thanks to a photogrammetry software, and import the 3D m...
Simulation of Pan-Tilt-Zoom Tracking for Augmented Reality Air Traffic Control
Using Augmented Reality (AR) technology for Air Traffic Control (ATC) holds great promise but comes with a number of technical challenges. In addition to displaying the position of surrounding aircraft, a zoomed-in view of a certain aircraf...
Performance Evaluation of HDR Image Reconstruction Techniques on Light Field Images
The reconstruction of high dynamic range (HDR) images from low dynamic range (LDR) images is a challenging task. Multiple algorithms are implemented to perform the reconstruction process for HDR images and videos. These techniques include, ...
