This research proposed an approach for automatic extraction of buildings from digital aerial imagery and
LiDAR data. The building patches are detected from the original image bands, normalized Digital Surface Model (nDSM)
and some ancillary data. Support Vector Machines (SVMs) and artificial neural network (ANNs) classifiers have been
applied individualey as member classifiers. In order to improve the obtained results, SVMs and ANNs have been combined in
serial, parallel and hybrid forms. The results showed that hybrid system has performed the best with an overall accuracy of
about 87.211% followed by parallel combination, serial combination, ANNs and SVMs with 84.709, 82.102, 77.605 and
74.288% respectively. |
