Delivery of omnidirectional video using saliency prediction and optimal bitrate allocation
(2020)In this work, we propose and investigate a user-centric framework for the delivery of omnidirectional video (ODV) on VR systems by taking advantage of visual attention (saliency) models for bitrate allocation module. For ... -
Analysing patterns of right brain-hemisphere activity prior to speech articulation for identification of system-directed speech
(2019)Autonomous speech-enabled applications such as speech-to-speech machine translation, conversational agents, and spoken dialogue systems need to be able to distinguish system-directed user input from “off-talk” to function ... -
Network interventions for managing the COVID-19 pandemic and sustaining economy
(2020)Sustaining economic activities while curbing the number of new coronavirus disease 2019 (COVID-19) cases until effective vaccines or treatments become available is a major public health and policy challenge. In this paper, ... -
Cache optimization models and algorithms
(2020)Caching refers to the act of replicating information at a faster (or closer) medium with the purpose of improving performance. This deceptively simple idea has given rise to some of the hardest optimization problems in the ... -
On the Efficiency of Sharing Economy Networks
(2020)Exchange of resources (or, services) over sharing economy networks is attracting increasing interest. Despite their broad applicability, many fundamental questions about their properties remain unanswered. We consider a ... -
Immersive Imaging Technologies: From Capture to Display
(2020)New immersive imaging technologies enable creating multimedia systems that would increase the viewer presence and provide an immersive experience. This half-day tutorial aims to give an overview of these new immersive ... -
Semantic Crowd Re-targeting: Implementation for Real-time Applications and User Evaluations
(2021)Crowd simulation is the act of simulating and controlling the dynamic movement of large groups of virtual characters. Crowd simulation is traditionally a complex and time-consuming process, requiring extensive manual effort ... -
Hierarchical Fourier Disparity Layer Transmission for Light Field Streaming
(2020)In this paper, we present a novel approach to efficiently transmit light fields in the Fourier Disparity Layer (FDL) representation using a binary hierarchical scheme. The FDL model consists of a set of additive layers ... -
Self-supervised Light Field View Synthesis Using Cycle Consistency
(2020)High angular resolution is advantageous for practical applications of light fields. In order to enhance the angular resolution of light fields, view synthesis methods can be utilized to generate dense intermediate views ... -
Soft Colour Segmentation On Light Fields
(2020)In this work we explore methods for allowing advanced colour editing on light field images to be performed. This investigation is twofold. First we look at soft colour algorithms to decompose images into colour layers and ... -
Towards Audio-Visual Saliency Prediction for Omnidirectional Video with Spatial Audio
(2020)Omnidirectional videos (ODVs) with spatial audio enable viewers to perceive 360° directions of audio and visual signals during the consumption of ODVs with head-mounted displays (HMDs). By predicting salient audio-visual ... -
A Case Study on the Use of Volumetric Video in Augmented Reality for Cultural Heritage
(2020)Interest in the use of augmented reality (AR) is currently growing alongside advances in visual display and 3D reconstruction technologies. With the integration of volumetric video (VV), AR can be enhanced with representations ... -
A Spatio-Angular Binary Descriptor for Fast Light Field Inter View Matching
(2020)Light fields are able to capture light rays from a scene arriving at different angles, effectively creating multiple perspective views of the same scene. Thus, one of the flagship applications of light fields is to estimate ... -
"What is, Becomes What is Right" A Conceptual Framework of Newcomer Legitimacy for Online Discussion Communities.
(2015)Online community newcomers can face challenges in community participation, acceptance and fostering member relationships. Consequently, a crucial behavioral strategy for community acceptance identified by previous research ... -
Light field style transfer with local angular consistency
(2021)Style transfer involves combining the style of one image with the content of another to form a new image. Unlike traditional two-dimensional images which only capture the spatial intensity of light rays, four-dimensional ... -
Image Decomposition using Geometric Region Colour Unmixing
(2020)In this paper, we propose a new geometric approach for image decomposition which aims to combine the advantages of two state of the art techniques. Given an input image, we first compute a palette of colours from the image ... -
Bridging the Blue
(Carnegie Mellon University, Pittsburgh: ETC Press, 2020,, 2020)Bridging the Blue is an attempt to harness tech-nology as an enabler of empathy through using its qualities and possibilities to challenge how we listen. Feedback to date suggests that Bridging the the Blue offers an ... -
A Benchmark for 3D Reconstruction from Aerial Imagery in an Urban Environment
(2021)This paper presents a novel benchmark to evaluate 3D reconstruction methods using aerial images in a large- scale urban scenario. In particular, it presents an evaluation of open-source state-of-the-art pipelines for ... -
The Semantic Combining for Exploration of Environmental and Disease Data Dashboard for Clinician Researchers
(CEUR Workshop Proceedings, 2020)While Semantic Web technologies facilitate the integration of heterogeneous data sources through the Resource Description Frame-work (RDF) and ontologies, they present an obstacle for non-technical researchers who want to ... -
Cost Analysis of Rural Roll-Out using long reach PON: Trading off Upfront Cost Under Uncertainty of User Take-up Rate
(2021)High deployment cost with respect to expected revenue is the main barrier to fiber-to-the-home (FTTH) roll-out in rural areas. This problem, as shown in this paper, is exacerbated by the uncertainty associated with the ...
