Re-Engineering Rate Distortion Optimisation in Modern Video Codecs Using a Per Clip Approach
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2023)The majority of internet traffic is video content. This drives the demand for video compression to deliver high quality video at low target bitrates. Optimising the parameters of a video codec for a specific video clip ... -
Deep Interactive Image Matting
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2022)Image Matting for Compositing is the cutting of an object from an image for background replacement. It is an interactive process fundamental to image editing. Useful matting algorithms both reduce the amount of interaction ... -

However, the psychoacoustics behind distance perception are quite complex, ... -
Virtual Radios, Real Services: Enabling End-to-End Network Slicing through Radio Virtualisation
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2021)This work aims to resolve some resource management problems that arise due to changes in the mobile network market and business models, brought by recent trends in commercial mobile networks, such as the widening range of ... -
Massive MIMO and Millimetre Wave Technologies: Design, Application and Integration with ML Techniques for 5G and Beyond Networks
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2021)Massive Multiple-Input-Multiple-Output (mMIMO) and millimetre Wave (mmWave) are key enabling technologies to realise omnipresent, scalable and dynamic 5-th Generation (5G) and beyond networks that provide seamless wireless ... -
Deep Cross-Modal Alignment in Audio-Visual Speech Recognition
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2021)Modern studies in cognitive psychology have demonstrated that speech perception is a multimodal process, as opposed to a purely auditory one with visual carryover as in the classic view. This led researchers to investigate ... -
Dipole-Dipole Coupling and Other Interaction Effects in Polar Dielectrics and Magnetic Relaxation of Single Domain Ferromagnetic Nanoparticles
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2021)The main purpose of this thesis is to provide the precise details of the very onerous calculations underlying our two published papers [1] and [2]. Thus, the latter can be better understood and utilised later for future ... -
Neural Turn-Taking Models for Spoken Dialogue Systems
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2021)In order to simulate naturalistic turn-taking behaviours, such as fast-turn switches, intentional overlap, backchanneling, and barge-in, spoken dialogue systems (SDSs) will need to have computational models of turn-taking ... -
Joint caching and communication for future wireless networks
Recently, caching the most popular content at network edges has emerged as a promising technique to avoid serving all requests from the core network through highly congested backhaul links. From the caching perspective, ... -
The impact of visual speech on neural processing of auditory speech
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2021)When we listen to someone speak, seeing their face can help us to understand them better, especially when there is background noise or other people speaking at the same time. Research examining the neural processes underlying ... -
Uncovering the effects of semantic context on the cortical processing of continuous speech using computational models of language
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2021)The semantic context in which spoken words appear will greatly shape how they are understood by the human brain. This understanding is underpinned by a hierarchical system that processes increasingly abstract features of ... -
Investigating the Neural Correlates of Cervical Dystonia and Temporal Discrimination using Neuroimaging based Computational Modelling and Multimodal Pattern Recognition
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2020)Movement disorders, such as Parkinson s disease and Dystonia, have traditionally been considered as disorders of impaired motor control resulting predominantly from dysfunction of the Basal Ganglia. However, there has been ... -
On the Design and Analysis of Indoor Millimetre-Wave Cellular Networks under Human Body Blockage
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2020)The wide spectrum available in the millimetre-wave band is key to provide enhanced capacity for the demands of the fifth-generation (5G) of cellular networks. However, the usage of millimetre-wave frequencies introduces a ... -
