Conference Proceeding
Peng, T., Jermyn, I., Prinet, V., Zerubia, J., & Hu, B. (2007). A Phase Field Model Incorporating Generic and Specific Prior Knowledge Applied to Road Network Extraction from VHR Satellite Images. In N. . M. Rajpoot, & A. . H. Bhalerao (Eds.), Proceedings of the British Machine Vision Conference 2007 (1-10). https://doi.org/10.5244/c.21.89

We address the problem of updating road maps in dense urban areas by extracting the main road network from a very high resolution (VHR) satellite image. Our model of the region occupied by the road network in the image is innovative. It incorporates...

A `Gas of Circles' Phase Field Model and its Application to Tree Crown Extraction (2007)
Conference Proceeding
Horváth, P., & Jermyn, I. (2007). A `Gas of Circles' Phase Field Model and its Application to Tree Crown Extraction. In 15th European Signal Processing Conference (EUSIPCO 2007), Poznan, Poland, September 3-7, 2007 ; proceedings

The problem of extracting the region in the image domain corresponding to an a priori unknown number of circular objects occurs in several domains. We propose a new model of a ‘gas of circles’, the ensemble of regions in the image domain composed of...

Hanbury (Eds.), Computer analysis of images and patterns: 12th International Conference (CAIP 2007), Vienna, Austria, August 27-29, 2007 ; proceedings (702-709). https://doi.org/10.1007/978-3-540-74272-2

We describe a model for tree crown extraction from aerial images, a problem of great practical importance for the forestry industry. The novelty lies in the prior model of the region occupied by tree crowns in the image, which is a phase field versio...

In 2007 International Workshop on Content-Based Multimedia Indexing ; proceedings (244-250). https://doi.org/10.1109/cbmi.2007.385418

Indexing and retrieval from remote sensing image databases relies on the extraction of appropriate information from the data about the entity of interest (e.g. land cover type) and on the robustness of this extraction to nuisance variables. Other ent... Read More about Indexing satellite images with features computed from man-made structures on the Earth’s surface.
