Conference Proceeding
Peng, T., Jermyn, I., Prinet, V., & Zerubia, J. (2008). An extended phase field higher-order active contour model for networks and its application to road network extraction from VHR satellite images. In D. Forsyth, P. Torr, & A. Zisserman (Eds.), Computer Vision - ECCV 2008 ; part III (509-520). https://doi.org/10.1007/978-3-540-88690-7_38

This paper addresses the segmentation from an image of entities that have the form of a 'network', i.e. the region in the image corresponding to the entity is composed of branches joining together at junctions, e.g. road or vascular networks. We pres... Read More about An extended phase field higher-order active contour model for networks and its application to road network extraction from VHR satellite images.

Extraction of main and secondary roads in VHR images using a higher-order phase field model (2008)
Conference Proceeding
Peng, T., Jermyn, I., Prinet, V., & Zerubia, J. (2008). Extraction of main and secondary roads in VHR images using a higher-order phase field model. In J. Chen, J. Jiang, & W. Förstner (Eds.), International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, part B3a (215-222)

This paper addresses the issue of extracting main and secondary road networks in dense urban areas from very high resolution (VHR, ~0.61m) satellite images. The difficulty with secondary roads lies in the low discriminative power of the grey-level di...

A Phase Field Model Incorporating Generic and Specific Prior Knowledge Applied to Road Network Extraction from VHR Satellite Images (2007)
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...

A New Phase Field Model of a `Gas of Circles' for Tree Crown Extraction from Aerial Images (2007)
Conference Proceeding
Horváth, P., & Jermyn, I. (2007). A New Phase Field Model of a `Gas of Circles' for Tree Crown Extraction from Aerial Images. In W. G. Kropatsch, M. Kampel, & A. 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...

This paper illustrates and extends an efficient framework, called the square-root-elastic (SRE) framework, for studying shapes of closed curves, that was first introduced in [2]. This framework combines the strengths of two important ideas - elastic...
