Segmentation d’objets curvilignes à l’aide des champs de markov sur un graphe d’adjacence de courbes issu de l’algorithme de la ligne de partage des eaux

Abstract

This paper presents a general framework to segment curvilinear objects in 2D images. A pre-processing step relies on mathematical morphology to obtain a connected line which encloses curvilinear objects. Then, a graph is constructed from this line and a Markovian Random Field is defined to perform objects segmentation. Applications of our framework are numerous: they go from simple surve segmentation to complex road network extraction in satellite images.
