Title :
Extraction of 3D information using overlay detection on SAR images
Abstract :
This paper presents a study of height recovery using overlay detection in semi-urban areas. The input data are a lonely SAR image and a map of the buildings. The first part of the paper presents the different steps of the proposed algorithm (primitive selection, overlay extraction and height recovery), and the second part is dedicated to the method evaluation on two SAR images of the same area but acquired with different incidence angles.
