Evaluation quantitative de méthodes d'extraction de rues : choix d'une référence de comparaison
Résumé
In the context of an automatic street extraction from remotely sensed images, we are concerned about defining some quantitative criteria for evaluating the performance of algorithms. The aim is to obtain a measure of the quality of the results delivered by any method. This purpose needs the definition of a reference in order to compare it with extracted objects. In this paper, existing references in matter of pattern recognition from geographical scenes will be reviewed. Then a methodology for extracting a relative reference is defined when the only information available is the remotely sensed image. Related quantitative criteria are also given. The complete methodology is finally applied on a high resolution image from an urban scene.
