Students Report from ACM Multimedia 2022
ACM Multimedia 2022 was held in a hybrid format in Lisbon, Portugal from October 10-14, 2022. This was the first local participation in three years for many participants, as the strict travel restrictions associated with Covid-19 in 2020 and 2021 made it difficult to participate locally by travelling out of the host and neighbouring countries. In Portugal, ...

Encouraging more Diverse Scientific Collaborations with the ConfFlow application
Introduction ConfFlow is an application to encourage people with similar or complementary research interests to find each other at conferences. How scientific collaborations are initiated, how people meet and how an intention is developed to work together is an open question. The aim of this follow-up initiative to ConfLab: Meet the Chairs! held at ACM MM ...
PhD thesis summaries
Title: A Conceptual Architecture and a Framework for Dealing with Variability in Mulsemedia Systems
The increasing interest in digital immersive experiences has drawn the attention of researchers into understanding human perception whilst adding sensory effects to multimedia systems such as VR (Virtual Reality) and AR (Augmented Reality) applications, multimedia players, and games. These so-called mulsemedia—multiple sensorial media—systems are capable of delivering wind, smell, vibration, among others, along with audiovisual ...
Title: A Three Layer System for Audio-visual Quality Assessment
The development of models for quality prediction of both audio and video signals is a fairly mature field. But, although several multimodal models have been proposed, the area of audiovisual quality prediction is still an emerging area. In fact, despite the reasonable performance obtained by combination and parametric metrics, currently there is no reliable pixel-based ...
Title: Quality of experience characterization and provisioning in mobile cellular networks
Traditionally, previous generations of mobile cellular networks have been designed with Quality of Service (QoS) criteria in mind, so that they manage to meet specific service requirements. Quality of Experience (QoE) has, however, recently emerged as a concept, disrupting the design of future network generations by giving clear emphasis on the actually achieved user experience. ...
Title: Quality of Experience and Access Network Traffic Management of HTTP Adaptive Video Streaming
The thesis focuses on Quality of Experience (QoE) of HTTP adaptive video streaming (HAS) and traffic management in access networks to improve the QoE of HAS. First, the QoE impact of adaptation parameters and time on layer was investigated with subjective crowdsourcing studies. The results were used to compute a QoE-optimal adaptation strategy for given ...
Title: Objects for spatio-temporal activity recognition in videos
This thesis investigates the role of objects for the spatio-temporal recognition of activities in videos. We investigate what, when, and where specific activities occur in visual content by examining object representations, centered around the main question: what do objects tell about the extent of activities in visual space and time? The thesis presents six works ...
Title: An action recognition framework for uncontrolled video capture based on a spatio-temporal video graph
The task of automatic categorization and localization of human action in video sequences is valuable for a variety of applications such as detecting relevant activities in surveillance video, summarizing and indexing video sequences or organizing a digital video library according to the relevant actions. However it remains a challenging problem for computers to robustly recognize ...
Title: Deep image representations for instance search
We address the problem of visual instance search, which consists to retrieve all the images within an dataset that contain a particular visual example provided to the system. The traditional approach of processing the image content for this task relied on extracting local low-level information within images that was “manually engineered” to be invariant to ...
Title: Improving instance search performance in video collections
This thesis presents methods to improve instance search and enhance user performance while browsing unstructured video collections. Through the use of computer vision and information retrieval techniques, we propose novel solutions to analyse visual content and build a search algorithm to address the challenges of visual instance search, while considering the constraints for practical applications. ...
Title: An Investigation Into Machine Learning Solutions Involving Time Series Across Different Problem Domains
In this thesis we will examine architectures and models for machine learning in three problem domains each of which are based around the use of time series data in time series applications. We set out to examine whether the architecture and model solutions in different problem domains will converge when optimised towards a similar solution ...
Title: Behavioural biometric identification based on human computer interaction
As we become increasingly dependent on information systems, personal identification and profiling systems have received an increasing interest, either for reasons of personalisation or security. Biometric profiling is one means of identification which can be achieved by analysing something the user is or does (e.g., a fingerprint, signature, face, voice). This Ph.D. research focuses on ...
