Integration of multi-source data for automated building extraction

PolyU Library Call No.: [THS] LG51 .H577P LSGI 2004 Khoshelham Digital building models are used in various applications and are traditionally acquired by manual digitization of aerial images in stereo view using photogrammetric stereoplotters. Manual digitization is a tedious and time-consuming task, which requires skilled operators and expensive equipments. Therefore, methods that can assist the operator in performing the entire or part of the task automatically are of great significance. Automated methods for extraction of buildings face a number of problems. Semi-automated approaches involve a considerable amount of interaction. Fully automated approaches that work solely based on a single source of data, suffer from the lack of robustness due to complexities involved in data as well as in buildings. In this thesis, a new approach is presented for semi-automated extraction of buildings from a single aerial image with minimum interaction. ...
