Abstract

In this paper, we propose a novel region-based perceptual grouping algorithm for road segment identifying in urban areas from high resolution spatial images. Unlike the conventional approaches which are based on edges, our grouping is carried out on region basis. An imagery scene is modeled by the spectrally homogeneous regions restrained in shape and size. Given a set of low level image features for each region, perceptual grouping is performed on the regions to generate a higher level of structure, from which road segments are extracted. In our unique approach, perceptual grouping is based on the similarity of spectral, orientation and proximity of the candidate regions. For this, a crisp classifier is employed for similarity measurement to find the road candidates; the road candidates are further merged into larger regions in terms of their orientation and adjacency. The road segments are extracted from these merged regions on geometric measurement of a candidate road segment. In order to evaluate the performance of the proposed algorithm, experiments are carried out on imagery of real scenes. The results showed the approach has the advantage of distinguishing roads from artifacts caused by parking lots and buildings.

OtherThe 6th International Conference on Information Technology and Applications (ICITA 2009) will be held in Hanoi, Vietnam on 9 - 12 November 2009. The conference is an annual event and is recognized as one of the major series of conferences in Information Technology (IT in short). ICITA continues to retain its tradition of high quality conference and will open up an opportunity for academics and industrial professionals worldwide to exchange their knowledge of the state-of-the-art research and development in information technology and applications, and to establish and extend professional networks. This conference addresses the importance that IT professionals stretch across narrowly defined subject areas and constantly acquire a global technical and social perspective. ICITA 2009 has offered such an opportunity to facilitate cross-disciplinary and social gatherings.
