Uncertainty factors in ecotoxicological risk management. (2006)
Presentation / Conference Contribution
Craig, P. S. (2006). Uncertainty factors in ecotoxicological risk management.

Uncertainty factors (also known as extrapolation or safety factors) are widely used in lower tier ecotoxicological risk management in order to allow for sources of variability and uncertainty for which there is only limited information. From the poin... Read More about Uncertainty factors in ecotoxicological risk management..

Mass Terms in the Skyrme Model (2006)
Presentation / Conference Contribution
Kopeliovich, V., Piette, B., & Zakrzewski, W. (2006). Mass Terms in the Skyrme Model.

We consider various forms of the mass term for the Skyrme model and their implications on the properties of baryonic states. We show that modifications of the mass term, without changing the asymptotic behaviour of the profile function at large r, ca... Read More about Mass Terms in the Skyrme Model.

An improved `gas of circles' higher-order active contour model and its application to tree crown extraction (2006)
Presentation / Conference Contribution
Horvath, P., Jermyn, I., Kato, Z., & Zerubia, J. (2006). An improved `gas of circles' higher-order active contour model and its application to tree crown extraction. In P. K. Kalra, & S. Peleg (Eds.), Computer Vision, Graphics and Image Processing: 5th Indian Conference, ICVGIP 2006, Madurai, India, December 13-16, 2006 ; proceedings (152-161). https://doi.org/10.1007/11949619_14

A central task in image processing is to find the region in the image corresponding to an entity. In a number of problems, the region takes the form of a collection of circles, e.g. tree crowns in remote sensing imagery; cells in biological and medic...

Computing statistics from a graph representation of road networks in satellite images for indexing and retrieval (2006)
Presentation / Conference Contribution
Bhattacharya, A., Jermyn, I., Descombes, X., & Zerubia, J. (2006). Computing statistics from a graph representation of road networks in satellite images for indexing and retrieval. In J. Tavares, & R. Jorge (Eds.), Computational modelling of objects represented in images : fundamentals, methods and applications : proceedings of the International Symposium CompIMAGE 2006 (Coimbra, Portugal, 20-21 October 2006) (97-100)

Retrieval from remote sensing image archives relies on the extraction of pertinent information from the data about the entity of interest (e.g. land cover type), and on the robustness of this extraction to nuisance variables (e.g. illumination). Most... Read More about Computing statistics from a graph representation of road networks in satellite images for indexing and retrieval.

Conditional Lower Previsions for Unbounded Random Quantities (2006)
Presentation / Conference Contribution
Troffaes, M. C. (2006). Conditional Lower Previsions for Unbounded Random Quantities. In J. Lawry, E. Miranda, A. Bugarin, S. Li, M. Ángeles Gil, P. Grzegorzewski, & O. Hryniewicz (Eds.),

In this paper, a theory of conditional coherent lower previsions for arbitrary random quantities, including unbounded ones, is introduced, based on Williams's notion of coherence, and extending at the same time unconditional theories studied for unbo...

Nonlinear models for the statistics of adaptive wavelet packet coefficients of texture (2006)
Presentation / Conference Contribution
Aubray, J., Jermyn, I., & Zerubia, J. (2006). Nonlinear models for the statistics of adaptive wavelet packet coefficients of texture. In 14th European Signal Processing Conference, 2006 (1-5)

Probabilistic adaptive wavelet packet models of texture provide new insight into texture structure and statistics by focusing the analysis on significant structure in frequency space. In very adapted subbands, they have revealed new bimodal statistic... Read More about Nonlinear models for the statistics of adaptive wavelet packet coefficients of texture.

A higher-order active contour model for tree detection (2006)
Presentation / Conference Contribution
Horvath, P., Jermyn, I., Kato, Z., & Zerubia, J. (2006). A higher-order active contour model for tree detection. In Y. Y. Tang, S. P. Wang, G. Lorette, D. S. Yeung, & H. Yan (Eds.), 18th International Conference on Pattern Recognition (130-133). https://doi.org/10.1109/icpr.2006.79

We present a model of a `gas of circles', the ensemble of regions in the image domain consisting of an unknown number of circles with approximately fixed radius and short range repulsive interactions, and apply it to the extraction of tree crowns fro...

The fitting of multifunctions: an approach to nonparametric multimodal regression (2006)
Presentation / Conference Contribution
Einbeck, J., & Tutz, G. (2006). The fitting of multifunctions: an approach to nonparametric multimodal regression. In A. Rizzi, & M. Vichi (Eds.), COMPSTAT 2006 : proceedings in computational statistics, 17th symposium held in Rome, Italy, 2006 (1251-1258)

In the last decades a lot of research has been devoted to smoothing in the sense of nonparametric regression. However, this work has nearly exclusively concentrated on fitting regression functions. When the conditional distribution of y|x is multimod... Read More about The fitting of multifunctions: an approach to nonparametric multimodal regression.

Analyzing Irish suicide rates with mixture models (2006)
Presentation / Conference Contribution
Sofroniou, N., Einbeck, J., Hinde, J., & Newell, J. (2006). Analyzing Irish suicide rates with mixture models. In Proceedings of the 21st International Workshop on Statistical Modelling: IWSM 2006, 3-7 July 2006, Galway, Ireland (474-481)

In the analysis of morbidity and mortality data, variance component models are commonly used to provide an improvement in the estimation of rates for small regions which typically show large variability. This article investigates Irish suicide data u... Read More about Analyzing Irish suicide rates with mixture models.
