摘要
This paper addresses the issue of cartographic database creation or update using high resolution SAR and optical images In cartographic applications, objects of interest are mainly buildings and roads. This paper proposes a processing chain to update building databases The approach is composed of two steps First, the presence of each database object is checked in the images Then, we verify if objects coming from an image segmentation should be added in the database To do those two steps. features are extracted from images in the neighborhood of the considered object. The object removal/inclusion in the database IS based on a score obtained by the fusion of features in the framework of Dempster Shafer evidence theory
