Viewpoint adaptation, or 'look-around' capability, is likely to be vital to the success of future immersive multimedia services such as 3D video-conferencing, virtual reality and 3DTV. This paper proposes a low complexity and efficient compression system for multiview images using quadtree disparity estimation and multiview synthesis. Previous approaches to the problem have generally involved t...

This research proposes an on-line incremental 3D reconstruction framework that can be used on telepresence robots or human robot interaction (HRI). The aim is a low cost solution that enables users to communicate and interact remotely experiencing the benefits of a face-to-face meeting. By exploring computers graphics techniques and spatial audio we intend to induce sensations of being physical...

Depth-image-based rendering (DIBR) oriented view synthesis has been widely employed in the current depth-based 3D video systems by synthesizing a virtual view from an arbitrary viewpoint. However, holes may appear in the synthesized view due to disocclusion, thus significantly degrading the quality. Consequently, efforts have been made on developing effective and efficient hole filling algorith...

Multi-view imaging (MVI) has attracted increasing attention recently, thanks to the rapidly dropping cost of digital cameras. This opens a wide variety of interesting new research topics and applications, such as virtual view synthesis, high-performance imaging, image/video segmentation, object tracking/recognition, environmental surveillance, remote education, industrial inspection, 3DTV, and ...

Novel view synthesis aims to synthesize new images from different viewpoints of given images. Most of previous works focus on generating novel views of certain objects with a fixed background. However, for some applications, such as virtual reality or robotic manipulations, large changes in background may occur due to the egomotion of the camera. Generated images of a large-scale environment fr...

This research focuses on the generation of soundscapes using unstructured sound databases for the sonification of virtual environments. The design methodology incorporates the use of concatenative synthesis to construct a sound environment using online community-provided sonic material, and an application of this methodology is described in which sound environments are generated for Google Stre...

Virtual view synthesis is one of the most important techniques to realize free viewpoint television and three-dimensional (3D) video. In this article, we propose a view synthesis method to generate high-quality intermediate views in such applications and new evaluation metrics named as spatial peak signal-to-noise ratio and temporal peak signal-to-noise ratio to measure spatial and temporal con...

This paper presents a novel approach for navigating in a Panorama-Based Virtual Environment (PBVE). A PBVE was constructed for the arbitrary view synthesis when navigating. Uses can interact with PBVE through augmented 3D graphic objects. Unlike traditional imagebased virtual environment (VE) systems in which the functions of presenting 3D geometry and human-system interaction are very limited,...
