Towards modelling cost and risks of infrequent events in the cargo screening process (2010)
Conference Proceeding
Sherman, G., Menachof, D., Aickelin, U., & Siebers, P. (2010). Towards modelling cost and risks of infrequent events in the cargo screening process. In Proceedings of the Operational Research Society Simulation Workshop 2010 (SW10)

We introduce a simulation model of the port of Calais with a focus on the operation of immigration controls. Our aim is to compare the cost and benefits of different screening policies. Methodologically, we are trying to understand the limits of disc... Read More about Towards modelling cost and risks of infrequent events in the cargo screening process.

Reputation-based security protocol for MANETs in highly mobile disconnection-prone environments (2010)
Conference Proceeding
Radenkovic, M., Zakhary, S. R., & Radenkovic, M. (2010). Reputation-based security protocol for MANETs in highly mobile disconnection-prone environments. In 2010 Seventh International Conference on Wireless On-demand Network Systems and Services (WONS) (161--167). https://doi.org/10.1109/WONS.2010.5437117

This paper is concerned with fully distributed reputation-based mechanisms that improve security in MANETS. We introduce a number of optimisations to the current reputation schemes used in MANETs such as selective deviation tests and adaptive expirat...

Bidirectional relighting for 3D-aided 2D face recognition (2010)
Conference Proceeding
Toderici, G., Passalis, G., Zafeiriou, S., Tzimiropoulos, G., Petrou, M., Theoharis, T., & Kakadiaris, I. A. (2010). Bidirectional relighting for 3D-aided 2D face recognition.

In this paper, we present a new method for bidirectional relighting for 3D-aided 2D face recognition under large pose and illumination changes. During subject enrollment, we build subject-specific 3D annotated models by using the subjects' raw 3D dat... Read More about Bidirectional relighting for 3D-aided 2D face recognition.

A new penalty term for the BIC with respect to speaker diarization (2010)
Conference Proceeding
Stafylakis, T., Tzimiropoulos, G., Katsouros, V., & Carayannis, G. (2010). A new penalty term for the BIC with respect to speaker diarization.

In this paper we examine a new penalty term for the Bayesian Information Criterion (BIC) that is suited to the problem of speaker diarization. Based on our previous approach of penalizing each cluster only with its effective sample size - an approach... Read More about A new penalty term for the BIC with respect to speaker diarization.

A novel framework to elucidate core classes in a dataset (2010)
Conference Proceeding
Soria, D., & Garibaldi, J. M. (2010). A novel framework to elucidate core classes in a dataset.

In this paper we present an original framework to extract representative groups from a dataset, and we validate it over a novel case study. The framework specifies the application of different clustering algorithms, then several statistical and visu... Read More about A novel framework to elucidate core classes in a dataset.

Fast wavelet-based pansharpening of multi-spectral images (2010)
Conference Proceeding
Mitianoudis, N., Tzimiropoulos, G., & Stathaki, T. (2010). Fast wavelet-based pansharpening of multi-spectral images.

Remote Sensing systems enhance the spatial quality of low-resolution Multi-Spectral (MS) images using information from Pan-chromatic (PAN) images under the pansharpening framework. Most decimated multi-resolution pansharpening approaches upsample the... Read More about Fast wavelet-based pansharpening of multi-spectral images.

Vorsprung durch Technik: multi-display learning spaces and art-historical method (2010)
Conference Proceeding
Bligh, B., & Lorenz, K. (2010). Vorsprung durch Technik: multi-display learning spaces and art-historical method.

The trajectory and heuristic success of Art History as a discipline has always been inseparably linked to the technical means of visualizing the material that is at its core. When in the late 19th century first analogous, then double-slide projection... Read More about Vorsprung durch Technik: multi-display learning spaces and art-historical method.

When worlds collide: combining Ordnance Survey and Open Street Map data (2010)
Conference Proceeding
Anand, S., Morley, J., Jiang, W., Du, H., Hart, G., & Jackson, M. (2010). When worlds collide: combining Ordnance Survey and Open Street Map data.

The context of this paper is the progress of national and international spatial data infrastructures such as the UK Location Programme and INSPIRE, contrasted against crowd-sourced geospatial databases such as Open Street Map. While initiatives such... Read More about When worlds collide: combining Ordnance Survey and Open Street Map data.
