Automated SEgmentation of Microtomography Imaging (ASEMI)
Funding source: ATTRACT project
Microtomography is an X-ray imaging technique similar to the medical CT scanner, and can be used to visualize the internal structures of objects in a non-invasive and non-destructive way. However, microtomography uses synchrotron radiation, an extremely powerful source of X-rays. This allows scans at much higher resolution and quality. Thanks to the phase contrast effect, it can also be used to image soft tissues without the need for contrast agents. Our partners on this project at ESRF have been using two of the microtomography beamlines (ID19 and BM05) for applications in Egyptology, through the investigation of animal mummies. In this application, trained specialists manually segment the volume into textiles, organic tissues, balm resin, ceramics and bones. This process is very time consuming, typically taking several weeks for a small animal mummy. In the near future, thanks to the construction of a new beamline (BM18), the same process is expected to be applied to human mummies, which would take considerably longer. The main objective of our project is to develop and use artificial intelligence techniques to automatically perform this laborious process. Following the principles of “Open Innovation, Open Science, Open to the World”, the developed algorithms, data sets, and results will be made available to the general public. This project has received funding from the ATTRACT project funded by the EC under Grant Agreement 777222.
The Pléiades satellite is the first satellite that captures three consecutive high resolution images of the same region within a relatively short time-frame. This enables researchers to use computer vision techniques to estimate the elevation of objects from the land surface. Researchers at CNES have developed a processing pipeline that is able to generate a 3D reconstruction of scenes captured by the Pléiades satellite. This technology makes it possible to update the digital elevation models on a daily basis. Nevertheless, the 3D reconstruction method has an inherent error margin and can also introduce distortions in the models. The aim of the SATINET project is to use images captured by Synthetic Aperture Radar from Sentinel-1 and adopt more advanced computer vision techniques to improve the quality of the existing 3D reconstruction model. This project will also finance an M.Sc. by research project in collaboration with CNES within the Department of Communications and Computer Engineering at the University of Malta to work on Crop classification.
VideO Light field Acquisition and REstoration (VoLARe)
The state-of-the-art in augmented-reality (AR), virtual-reality (VR) and cinematic recording is the Lytro Immerge 2.0, using a rig of ninety-five (95) cameras. This technology allows digital refocusing after capture and facilitates 3D modelling and the realistic integration of computer-generated content. The major hurdle is that this system is too expensive for most productions. The VoLARe project involves the design and development of a low-cost video light field capturing prototype which aims to reduce the number of cameras by a factor of nine (9) thus reducing the throughput down to 30 Gbps. The major challenge in this project is to develop spatial, angular and temporal restoration techniques to improve the quality of the captured video light field.
Face Image Restoration using Deep learning (Deep-FIR)
Funding source: FUSION R&I Technology Development Programme
The Deep-FIR project aims to design and implement a face image restoration algorithm that is able to restore very low-resolution facial images captured by CCTV systems with unconstrained pose and orientation. Apart from improving the quality of the restored facial images, this project intends to reduce the complexity, and therefore the time needed to enhance an image or video frame. The developed algorithm will be tested on real-world CCTV videos and compared against existing video forensic tools used by forensic experts in their labs. Project Deep-FIR financed by the Malta Council of Science & Technology, for and on behalf of the Foundation of Science and Technology, through the FUSION: R&I Technology Development Programme.

SATellite data Fusion and Imaging Resolution Enhancement (SAT-FIRE)
Funding source: Space Research Fund programme
The main objectives of the SAT-FIRE project is to improve the spatial resolution challenges of the current Earth Observation (EO) Satellite systems by fusing complementary data from different spatial images from Sentinel-2 and Sentinel-3 data to improve both spatial and temporal resolution and quality of satellite images. This will allow for more accurate predictions of marine currents, aiding divers, search and rescue operations and coastal monitoring. This is an interdisciplinary research project which lies at the intersection of satellite image processing, remote sensing, data fusion and hydro-dynamical modelling. This project is financed by the Space Research Fund programme of the Malta Council of Science and Technology and is supported by the European Space Agency (ESA).

The ALICE experiment at the Large Hadron Collider at CERN studies the quark gluon plasma thought to have existed at the start of the Big Bang. Due to the high interaction rate in the experiment resulting from the collisions of heavy-ion particles, particle tracks produced in ALICE's detectors are often characterised by high occupancy and high noise. Members of the Data Science Research Group (DSRG) collaborate with two such detectors. In the case of the Time Projection Chamber, the objective is to identify low-momentum (low radius) helices which are not useful for physics analyses. On the other hand, in the High Momentum Particle IDentification detector, the aim is to identify elliptical patters from which the Cherenkov angle can be calculated.

Algorithm development for Antenna Intelligent Design Aids
Funding: EUR 3000
Duration: 2 years
Funding source: University
Start date: October 2007
Antenna intelligent design aids (AIDA) have so far been restricted to the application of efficient search algorithms such as the Genetic Algorithm and Simulated Annealing Algorithm. One can therefore comment that antenna CAD is somewhat lagging in this area when compared to CAD in other disciplines. This lack of development can be attributed to various reasons such as technical difficulties in the characterisation and classification of antenna design knowledge, lack of fast rigorous models for EM analysis and the lack of trust and conviction in having these design aids working in an effective way. In the longer term, however, this area of research can result in higher pay offs by helping in the timely design of terminal antennas at the right cost. This research project will focus on developing algorithms suitable for AIDA.

Tunable Antennas for Mobile RF Terminals Funding: EUR 22,904
Duration: 2 years
Funding source: University
Start date: September 2006
New antenna structures that exhibit multi-band and multi-function characteristics are required to sustain and increase the widespread use of wireless communication systems. Antenna bandwidth is a function of volume and usually mobile devices operate on narrowband channels rather than a single wide-band channel. This is very true of GSM as well as UMTS. Given this condition one can use a very small tunable antenna that switches frequencies in real time. This study will research into new structures to obtain tunable elements suitable for a number of different protocols, such as UMTS, WiFi and GSM.
Content Based Multimedia Retrieval with Ordered Relevance Feedback Funding: EUR 30,700
Duration: 2 years
Funding source: RTDI
Start date: December 2005
Searching the Internet for information using keywords is something that everybody practices and is an efficient way how to retrieve information from an otherwise chaotic repository. This project extends this searching capability to multimedia objects. This is a hard problem since no known technique yet exists that enables a computer to extract the semantics of a video clip, image etc. This project therefore proposes to use ordered relevance feedback from the users to improve the performance of the multimedia search system.
