This paper describes the approach for detecting the building facade using geometric constrain. A planar building facade is only considered. Most of the building facade has the form of a rectangle, which is produced by two or more vertical and horizontal lines, which are orthogonal to each other on the building. The parallel lines in the 3D space are projected onto lines in the image plane that are...
Classification of urban areas from a density measure is required in many application fields. For instance, propagation models for cellular radio networks are parameterized by coefficients whose value is linked to the nature of the soil. Geomarketing is also interested in knowing the population concentration (urban, suburban …). This paper presents the first results about the construction of an algorithm...
This paper presents a segmentation method that exploits object based region merging to delineate the context of the image under investigation. There are two main steps. Initially, primitive objects are obtained by morphological operations that generate spectrally homogenous primitives. We assume that primitives are components of semantic objects that are of interest. Next, these primitives therefore...
The present paper introduces an agent-based approach for clustering geographical data. In this approach, a multi-agent architecture is proposed. It consists of three competence levels: specialized gatherers (G-Agents), breakers (B-Agents), mappers (M-Agents). Each of these agents have particular role in the process of segmentation. Using biclustering, the approach combines the different views of the...
