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...

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.

Nonlinear models for the statistics of adaptive wavelet packet coefficients of texture (2006)
Conference Proceeding
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.

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...
