Congratulations to Philip Kelly
The title of Philip's thesis is "Pedestrian Detection and Tracking using Stereo Vision Techniques".
He completed his PhD in the Centre for Digital Video Processing (CDVP), Adaptive Information Cluster (AIC) and the School of Electronic Engineering, DCU under the supervision of Dr. Noel E. O’Connor.
Philip is currently working as a post-doctoral researcher with the CDVP.
Brief description of Project:
Accurate detection and tracking of pedestrians are two essential components required by a variety of applications that include, amongst others, Ambient Intelligence, automated surveillance, image compression and content-based multimedia storage and retrieval. Given this large number of potential applications, pedestrian detection and tracking has become an extremely active research area in computer vision. This has resulted in a significant amount of prior art proposing pedestrian segmentation techniques using a myriad of approaches. Many of the person detection techniques described so far in the literature work well in controlled environments, such as laboratory settings with a small number of people. This allows various assumptions to be made that simplify this complex problem. The performance of these techniques, however, tends to deteriorate when presented with unconstrained environments where pedestrian appearances, numbers, orientations, movements, occlusions and lighting conditions violate these convenient assumptions. Recently, 3D stereo information has been proposed as a technique to overcome some of these issues and to guide pedestrian detection.
This thesis presents such an approach, whereby after obtaining robust 3D information via a novel disparity estimation technique, pedestrian detection is performed via a 3D point clustering process within a region-growing framework. This clustering process avoids using hard thresholds by using bio-metrically inspired constraints and a number of plan view statistics. This pedestrian detection technique requires no external training and is able to robustly handle challenging real-world unconstrained environments from various camera positions and orientations. In addition, this thesis presents a continuous detect-and-track approach, with additional kinematic constraints and explicit occlusion analysis, to obtain robust temporal tracking of pedestrians over time.

DCU to lead Multi-Million Euro Research in High-Tech Automatic Language Translation
Dublin City University is to lead a multi-million euro research partnership funded by Science Foundation Ireland (SFI) that will develop the next generation of high tech automatic language translation.
This five-year research programme will transform an important sector of Ireland’s global software business – localisation - as well as a key driver of the global content distribution industry.
DCU is collaborating in the project with academic partners, UCD, UL and TCD, and with renowned global technology leaders, IBM, Microsoft, Symantec, Dai Nippon Printing, and Idiom Technologies as well as key Irish SMEs, Alchemy, VistaTech, SpeechStorm and Traslan.
The Minister for Enterprise and Employment, Michael Martin, today announced the award of €16.8m to the project by SFI, and the industry partners are contributing €13.6m in materials, research services and additional funding.
Ireland already has a substantial global footprint in the localisation industry – the process of adapting digital content, download manuals, software and other materials, to different languages and cultures.
The President of DCU, Professor Ferdinand von Prondzynski, said: ”This welcome funding is a great endorsement of DCU’s international research capability. It means that DCU is now leading two SFI Centres for Science, Engineering and Technology (CSETs) – in biomedical diagnostics and localisation technology – that have won the largest-ever SFI funding in the state”
The Irish project will tackle three critical problems for the Localisation Industry:
- Volume: The amount of content to be translated and localised to the destination culture and environment is growing rapidly and massively outstrips the supply of human translators.
- Access: Powerful, small devices such as mobile phones and PDAs require novel technologies integrating speech and text to support “on the move” delivery of, and access to multilingual information.
- Personalisation : A new demand has rapidly emerged for the adaptation of a huge amount of multilingual content now available on the web, for individual needs . It needs “instant” localisation and personalisation to meet the demands of the users.
Professor Josef van Genabith, Director of the new Centre said: "Localisation as an industrial process was developed in Ireland. We have a unique concentration of university- and industry-based research and development expertise in language technologies, machine translation, speech processing, digital content management and localisation. The research centre is going to pool that expertise and develop the next generation of language and content management technologies to support and develop the localisation industry.”

DCU Researchers Win Top International Paper Prize
Over the last five years Dr. Dermot Brabazon, Dr. Ahmed Issa and Prof. Saleem Hashmi of the School of Mechanical and Manufacturing Engineering and the Materials Processing Research Centre (MPRC) have developed two laser micromachining processes which allow for the production of channels and voxels with highly repeatable micrometer level resolution. Devices fabricated with this developed technology can be used for applications such as microfluidic lab on a chip, strain measurement, sub-micrometer cooling systems and various photonic guiding systems.
The paper was entitled, Laser System Automation using LabVIEW and PCI E-Series Board for 3D Internal Micromachining. This work illustrated the sophisticated automated 3D Nd:YVO4 and CO2 laser micro fabrication facilities that were developed. In order to achieve the precise control, CAD processing, laser firing, 3D sample movement and thermal field modelling software were developed. In addition, in order to characterise the high efficiency achieved from these processes, an in house built automated channel and voxel profiler was used.
NI Days, which has been running for the past decade, gives engineers and scientists from across the UK & Ireland an opportunity to learn how the latest developments in computer-based measurement and automation increase productivity and lower cost through graphical system design and virtual instrumentation
The prize includes flight and accommodation to NI Week in Austin, TX, next year, a plaque and LEGO Mindstorms NXT.

Congratulations to Kealan McCusker
The title of Kealan's thesis is "Cryptographic key distribution in wireless sensor networks: a hardware perspective".
He completed his PhD in the Centre for Digital Video Processing (CDVP), Adaptive Information Cluster (AIC) and the School of Electronic Engineering, DCU under the supervision of Dr. Noel E. O’Connor.
Kealan is currently working as a post-doctoral researcher with the CDVP.
Brief description of Project:
In this work the suitability of different methods of symmetric key distribution for application in wireless sensor networks are discussed. Each method is considered in terms of its security implications for the network. It is concluded that an asymmetric scheme is the optimum choice for key distribution. In particular, Identity-Based Cryptography (IBC) is proposed as the most suitable of the various asymmetric approaches. A protocol for key distribution using identity based Non-Interactive Key Distribution Scheme (NIKDS) and Identity-Based Signature scheme is presented. The protocol is analysed on the ARM920T processor and measurements were taken for the run time and energy of its components parts. It was found that the Tate pairing component of the NIKDS consumes significant amounts of energy, and so it should be ported to hardware. An accelerator was implemented in 65nm CMOS technology and area, timing and energy figures have been obtained for the design. Initial results indicate that a hardware implementation of IBC would meet the strict energy constraint of a wireless sensor network node.
This project was generously funded by Enterprise Ireland (EI) and Science Foundation Ireland (SFI).

Congratulations to George Mitchell
The title of George's thesis is "Evolutionary Computation Applied to Combinatorial Optimisation Problems ".
He completed his PhD at the school of Electronic Engineering's Artificial Life research group while under the supervision of Professor Barry McMullin. The Artificial Life research group forms part of the Research Institute for Networks and Communications Engineering (RINCE), a national centre for excellence in Information and Communications Technology (ICT) based at Dublin City University.
Brief description of Project:
George's thesis addresses the issues associated with conventional genetic algorithms (GA) when applied to hard optimisation problems. In particular it examines the problem of selecting and implementing appropriate genetic operators in order to meet the validity constraints for constrained optimisation problems. The problem selected is the travelling salesman problem (TSP), a well known NP-hard problem.
Following a review of conventional genetic algorithms, this thesis advocates the use of a repair technique for genetic algorithms: GeneRepair. George evaluated the effectiveness of this operator against a wide range of benchmark problems and compare these results with conventional genetic algorithm approaches. A comparison between GeneRepair and the conventional GA approaches was made in two forms: firstly a handcrafted approach compared GAs without repair against those using GeneRepair. A second automated approach was then presented which utilises a meta-genetic algorithm to examine different configurations of operators and parameters. Through the use of a cost/benefit (Quality-Time Tradeoff) function, the user can balance the computational effort against the quality of the solution and thus allow the user to specify exactly what the cost benefit point should be for the search.
Results identified the optimal configuration settings for solving selected TSP problems. These results show that GeneRepair when used consistently generates very good TSP solutions in an extremely efficient manner, in both time and number of evaluations required.
There are many areas in which the finding of this work could be applied. The findings have definite applications in permutation based problems found in mathematics, engineering and computer science contexts. There are many other areas of high complexity ( e.g. Synthetic Biology) which at present are in the early stages of research. One factor which inhibits research in these areas is the cost of computation, this factor could be addressed through the use of the techniques discovered in the course of this work.

Congratulations to Paul Ferguson
The title of Paul's thesis is "Index Ordering by Query-Independent Measures".
He completed his PhD in the Centre for Digital Video Processing (CDVP), Adaptive Information Cluster (AIC) and the School of Computing, DCU under the supervision of Prof. Alan Smeaton.
Brief description of Project:
Rather than simply utilising more computing resources in order to perform retrieval on large text collections, we investigated ways in which to only search a limited amount of the collection at query-time, in order to speed up this retrieval process (as well as allowing retrieval to be carried out with limited computing resources). Although, in doing this we aimed to limit the loss in retrieval efficacy (in terms of accuracy of results).
In order to do this we identified a number of different query-independent measures that can approximate the documents' query-independent quality in the collection, rather than relying solely on a term-weighting approach to determine the importance of a document. In this way we can choose to limit the amount of information to search through, by eliminating the documents of lesser importance, which not only makes the search more efficient, but should also limit any loss in retrieval accuracy.
In our work we applied a number of traditional combination techniques, as well as machine learning approaches to the task of combining these measures together, to provide a more accurate overall measure. We also provided techniques to allow documents to be effectively eliminated from a sorted inverted index while retaining the same level of performance. This research should allow fast and effective retrieval of large collections of documents be carried out much more efficiently than using traditional retrieval techniques, while also retaining the same level of accuracy for a typical web user.

Congratulations to Ciarán Ó Conaire
He completed his PhD in the Centre for Digital Video Processing (CDVP), Adaptive Information Cluster (AIC) and the School of Electronic Engineering, DCU under the supervision of Dr. Noel E. O’Connor.
The difficulty of fusing data from multiple sources of information for automated visual analysis was addressed in two areas of computer vision: adaptive detection and adaptive object tracking. The work on adaptive object detection explores a new paradigm in dynamic parameter selection, by selecting thresholds for object detection to maximise agreement between pairs of sources.
Object tracking, a complementary technique to object detection, was also explored in a multi-source context and an efficient framework for robust tracking, termed the Spatiogram Bank tracker, was proposed as a means to overcome the difficulties of traditional histogram-based tracking. While general frameworks for data fusion were developed, the fusion of thermal infrared video with standard visual video was specifically targeted. Potential applications include: pervasive human-computer interaction and automated surveillance.

Success for Industry-Academia Partnership
This project allows for a synergistic interaction between industry and academia. According to Ben Breen, Head of R&D at ABS Production Wexford, “The innovation partnership is an economical way of getting vital research done, and for us, it means that James’ advanced knowledge can become an invaluable asset to ABS.” The benefits for DCU are clear: “The funding and support from the Innovation Partnership Programme was an enabler for the research that was undertaken……..Conducting this type of applied research means that we get to apply our skills to solving practical problems”, said Dermot Brabazon, a lecturer with DCU who supervised the project.
Both parties are so pleased with the outcome of the project that they will be re-applying for funding to upgrade Mr. Wall’s research to PhD level.
