Minimization of Cyber Security Threats Caused by COVID-19 Pandemic.
(Springer, 2021-02-25)While the world is preoccupied in its struggle with the Coronavirus pandemic, cyber-criminals are busy every day, spreading their own viruses, by phishing emails, data breaches, frauds, denials of service, and taking ... -
A Low-complexity Wavelet-based Visual Saliency Model to Predict Fixations
(IEEE, 2020-12-28)A low-complexity wavelet-based visual saliency model to predict the regions of human eye fixations in images using low-level features is proposed. Unlike the existing wavelet-based saliency detection models, the proposed ... -
Efficient HEVC-to-VVC Transcoder Based On A Bayesian Classifier For The First Quadtree Depth Level
(IEEE, 2020-09-30)In the coming years, the Versatile Video Coding (VVC) standard will be launched to replace the current High Efficiency Video Coding (HEVC) standard, making it necessary to find efficient methods to convert existing multimedia ... -
Virtual Pottery: Deformable Sound Shape Modelling and Fabrication
(IEEE, 2020-09-29)We introduce a novel system and technique for materialising the deformable shapes of sound-resonance on 3D objects. This technical framework presents a novel approach using a series of simple processes to manage complex ... -
Robots and Uncertainty: An investigation into the impact of the aesthetic visualisation on people’s trust of robots.
(2020-12-13)Human senses have evolved to pick-up on sensory cues. Beyond our perception, they play an integral role in our emotional processing, learning, and interpretation. They are what help us to sculpt our everyday experiences ... -
A Review of Cyber-Ranges and Test-Beds: Current and Future Trends
(MDPI, 2020-12-13)Cyber situational awareness has been proven to be of value in forming a comprehensive understanding of threats and vulnerabilities within organisations, as the degree of exposure is governed by the prevailing levels of ... -
Improving HEVC Coding Efficiency Using Virtual Long-Term Reference Pictures
(2020-10-13)Inter-frame prediction in HEVC uses two types of reference pictures: short-term and long-term. Out of these long-term reference (LTR) pictures enable exploiting correlation among frames with extended ... -
Application of Artificial Intelligence and Machine Learning in Producing Actionable Cyber Threat Intelligence
(Springer, 2021-01-07)Cyber Threat Intelligence (CTI) can be used by organisations to assist their security teams in safeguarding their networks against cyber-attacks. This can be achieved by including threat data feeds into their networks ... -
Online tracking of ants based on deep association metrics: method, dataset and evaluation
(Elsevier, 2020-02-21)Tracking movement of insects in a social group (such as ants) is challenging, because the individuals are not only similar in appearance but also likely to perform intensive body contact and sudden movement adjustment ... -
A Fuzzy Cooperative Localisation Framework for Underwater Robotic Swarms
(MDPI, 2020-09-25)This article proposes a holistic localisation framework for underwater robotic swarms to dynamically fuse multiple position estimates of an autonomous underwater vehicle while using fuzzy decision support system. A number ... -
Robotic Chinese language tutor: personalising progress assessment and feedback or taking over your job?
(Emerald, 2020-07-06)Purpose: The shortage of Chinese language teachers have been identified as a pressing issue globally. This paper aims to respond to the needs by investigating and designing the learning innovation with autonomous programmable ... -
Personal response systems through the prism of students' experiences
(Wiley, 2020-07-13)Personal response systems (PRSs) today offer an opportunity to the field of education in terms of improving teaching and learning outcomes through active engagement in classrooms. The present paper investigates students' ... -
Multimedia Quality of Experience (QoE): Current Status and Future Direction
(MDPI, 2020-07-20)Quality of Experience (QoE) is becoming an important factor of User-Centred Design (UCD). The deployment of pure technical measures such as Quality of Service (QoS) parameters to assess the quality of multimedia applications ... -
Investigating aesthetics to afford more ‘felt’ knowledge and ‘meaningful’ navigation interface design
(Information Visualisation Society, 2020-09-17)Aesthetically manipulating the visual variables of a navigation interface design has the potential for substantial improvements in the interpretation of, and subsequent navigational choices made resulting from that design. ... -
iCUS: Intelligent CU Size Selection for HEVC Inter Prediction
(IEEE, 2020-08-03)The hierarchical quadtree partitioning of Coding Tree Units (CTU) is one of the striking features in HEVC that contributes towards its superior coding performance over its predecessors. However, the brute force evaluation ... -
COVID-19: #Working From Home. Quite Enjoyed It. Surprised Myself.
(IADIS, 2020-07-21)As more than a third of the world's population is now in lock-down, we are seeing COVID-19 not only having serious implications on people's health but also having a significant knock-on effect on their livelihoods. A recent ... -
Virtual Frames as Long-Term Reference Frames for HEVC Inter-Prediction
(IEEE, 2020-03-23)High Efficiency Video Coding(HEVC) employs both past or future frames when encoding the current frame in a video sequence. This paper proposes a framework for using virtual reference frames, to achieve increased coding ... -
A Decoding-Complexity and Rate-Controlled Video-Coding Algorithm for HEVC
(MDPI, 2020-07-16)Video playback on mobile consumer electronic (CE) devices is plagued by fluctuations in the network bandwidth and by limitations in processing and energy availability at the individual devices. Seen as a potential solution, ... -
Towards understanding speciation by automated extraction and description of 3D foraminifera stacks
(IEEE, 2020-05-18)The sheer volume of 3D data restricts understanding of genetic spe- ciation when analyzing specimens of planktonic foraminifera and so we develop an end-to-end computer vision system to solve and ex- tend this. The observed ...
