Inflection point model under phase field higher-order active contours for network extraction from VHR satellite images.

El Ghoul, A. and Jermyn, I.H. and Zerubia, J. (2009) 'Inflection point model under phase field higher-order active contours for network extraction from VHR satellite images.', in 17th European Signal Processing Conference 2009 ; proceedings. Piscataway, NJ: IEEE, pp. 607-611.

Abstract

The segmentation of networks is important in several imaging domains, and models incorporating prior shape knowledge are often essential for the automatic performance of this task. We incorporate such knowledge via phase fields and higher-order active contours (HOACs). In this paper: we introduce an improved prior model, the phase field HOAC `inflection point' model of a network; we present an improved data term for the segmentation of road networks; we confirm the robustness of the resulting model to choice of gradient descent initialization; and we illustrate these points via road network extraction results on VHR satellite images.
