    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 ...

    Definitions of Crowdsourced Network and QoE Measurements

    1 Introduction and Definitions Crowdsourcing is a well-established concept in the scientific community, used for instance by Jeff Howe and Mark Robinson in 2005 to describe how businesses were using the Internet to outsource work to the crowd , but can be dated back up to 1849 (weather prediction in the US). Crowdsourcing has enabled a ...

    Report from ACM SIG Heritage Workshop

    “What does history mean to computer scientists?” – that was the first question that popped up in my mind when I was to attend the ACM Heritage Workshop at Minneapolis few months back. And needless to say, the follow up question was “what does history mean for a multimedia systems researcher?” As a young graduate student, I ...

    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: 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

    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. ...

    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 ...
