A Point Process for Fully Automatic Road Network Detection in Satellite and Aerial Images
Résumé
In this paper, we introduce a new model for road detection, based on the multiple birth and death (MBD) optimization algorithm, recently proposed for counting populations of trees or flamingos. We discuss the choice of the energy function guaranteeing accurate detections of both junctions and parallel roads, and preserving the connectivity of the road network despite the occlusions in high resolution images. We also propose here a novel local filter used as a preprocessing step, for detecting roads, and involved in the definition of the energy function.
