This month our latest research will be presented at the 2019 IEEE International Conference on Image Processing (ICIP) in Taipei, Taiwan. This is the premier event for image and video processing featuring international researchers and experts in this field.
We will present a Video Quality Metric that uses a deep autoencoder to train a model for video quality prediction. The presentation will be on Tuesday, 24 September at noon as part of a wider session on Novel Approaches for Image & Video Quality Assessment.
My paper, along with research by accepted authors, is currently available as a free download on IEEE Xplore until 25 September 2019. I hope you’ll download it and share any insights, feedback, and questions with me.
QxLab took a couple of days away from our desks for a co-located writing workshop. Basing ourselves in one of UCD’s new University Club meeting rooms, we spent two days working on our research writing. A starter session reflected on writing style and discussed where to publish. We practiced with some free writing and structured writing exercises and reviewed Brown’s 8 questions as a set of prompts.
Who are intended readers? (3-5 names)
What did you do? (50 words)
Why did you do it? (50 words)
What happened? (50 words)
What do results mean in theory? (50 words)
What do results mean in practice? (50 words)
What is the key benefit for readers (25 words)
What remains unresolved? (no word limit)
These questions, originally devised by Robert Brown but popularized by Rowena Murray, are a great way to get a writing retreat going. The rest of the sessions were spent progressing our writing towards our personal writing objectives – a bit like a natural language “Hackathon”.
For the final session we chose a short piece of own own writing and shared them for a non-judgemental peer review session where the author could choose the scope for their own feedback. A lot of the feedback followed common themes as we fell into similar traps with our writing.
A recent twitter thread offered a lot of advice we could relate to and a key take home message was to remember was that when you read published papers you only see the finished article. The papers you read have been through countless iterations and review feedback sessions from co-authors, reviewers and copy editors. Don’t compare your first draft to a published paper!

Today QxLab’s Dr Abubakr Siddig presented collaborative work on immersive multimedia. As part of the ACM MMSys conference in University of Massachusetts Amherst Campus, the International Workshop on IMmersive Mixed and Virtual Environment Systems, MMVE 2019 is celebrating its 11th edition.
The paper, Fusion Confusion: Exploring Ambisonic Spatial Localisation for Audio-Visual Immersion Using the McGurk Effect, looked at the relationship between visual cues and spatial localisation for speech sounds.
The paper found that the McGurk Effect, where visual cues for sounds override what you hear, occurs for spatial audio but is not sensitive to whether the speech sound is aligned in space with the lips of the speaker.
The research, carried out by QxLab’s UCD based researchers and funded by two SFI centre’s CONNECT and INSIGHT.
Well done to AbuBakr, the presentation and demo were well received by the workshop attendees.
QxLab has two papers at the Irish Signals and Systems Conference in Maynooth University today. MSc student, Tong Mo presented work of speech Quality of Experience. Her research investigated how computer models for speech quality prediction in systems such as Skype or Google Hangouts. She developed an algorithm to minimise errors in the presence of jitter buffers.
A second paper was presented by PhD candidate Hamed Jahromi entitled, “Establishing Waiting Time Thresholds in Interactive Web Mapping Applications for Network QoE Management.” Hamed’s work looked at the perception of time in web applications. Is an additional delay of half a second noticeable if you have already waited 5 seconds for a Google Map page to load? Time is not absolute and Hamed wants to understand the impact of delays on web applications in order to optimise network resources for interactive applications other than speech and video streaming. This work was co-authored with Delcan T. Delaney from UCD Engineering and Brendan Rooney from UCD Psychology.
This research was sponsored by UCD School of Computer Science and the SFI CONNECT Centre for Future Networks.
I was back at the RDS in Dublin visiting the BT Young Scientist and Technology Exhibition. Beginning in 1963, the exhibition concept was created by to UCD academics from the School of Physics. Fast forward to 30 years ago and I participated for the first of two visits. Arriving in again to visit thirty years later, I was struck by the professional finish of posters. So much has improved, but I still love the hand made stands and eye catching props to lure you into a project. As you can see from the newspaper clipping, our project may have involved a lot of hot air but I recall there was some scientific rigour to our methodology!
I met 2019 winner of the BT Young Scientist and Technology Exhibition, Adam Kelly, while judging the national finals of SciFest 2018 where he also won first prize. As a judge I was struck by his demonstration of all the attributes of a quality scientist: imagination, methodology and a great ability to communicate the work. He knew what he had done and was able to explain what he had not done, and why. Adam’s project for SciFest was entitled ‘An Open Source Solution to Simulating Quantum Computers Using Hardware Acceleration’ and was the overall winner out of more than 10,000 students competed in the regional heats to progress to the national SciFest 2018 final.
The event is an inspiring way to start the year: seeing the curiosity and scientific rigour on display by second level students who are motivated not by the prizes but by the desire to explore interesting questions.
QxLab’s Alessandro Ragano was in London’s Abbey Road Studio with his team ‘the Tailors’. The ‘Tailors’ helped find a way to provide an artificial companion for singers and songwriters. Taking lyrics and sentiment using Microsoft’s Cognitive APIs.
The 24 hour challenge, aimed to reinvent music innovation and production in collaboration with Microsoft to transform the way we create and experience music. Top industry mentors will assist participants as they work together to create solutions and explore questions.
The SFI CONNECT research centre for future networks project has funded the recruitment of a new postdoctoral research fellow at QxLab. Dr AbuBakr Siddig completed a PhD at University College Dublin and an MSc in Blekinge Institute of Technology, Sweden. He brings experience in digital signal processing and 802.11 wireless networking to the group. Welcome AbuBakr!
In recognition of his contributions to the profession, Andrew has been elevated to Senior Member status in the IEEE. And he even got a nice wooden plaque to prove it!
The IEEE (Institute of Electrical and Electronics Engineers) is a professional association with over 430,000 members worldwide and is active in related industry standards, conferences, and publications.
As part of the SFI 2018 PhD Recruitment Programme, Dr Andrew Hines, who joined Insight@UCD as a funded investigator during the summer, has recruited Alessandro Ragano as a PhD student. After completing his MSc at Politecnico di Milano, Alessandro spent time as a research assistant at Fraunhofer IIS. He will be co-supervised by Dr Emmanouil Benetos of the Alan Turing Institute and Queen Mary University of London (QMUL). As part of his PhD programme Alessandro will be spending one year in London at the ATI headquarters next door to the British Library. His research will investigate using data-driven quality prediction models for digitally restored audio archives. Welcome to QxLab and Insight@UCD Alessandro.
