The statistical information that is modeled using spectral, shape, and position data of individual objects, and structural information that is modeled in terms of spatial alignments of neighboring object groups are encoded in a graph structure that contains the primitive objects at its vertices, and the edges connect the potentially related objects. Experiments using WorldView-2 data show that hierarchical clustering of these vertices can find high-level compound structures that cannot be obtained using traditional techniques. © 2011 IEEE.Englishalignment detectiongraph-based representationhierarchical clusteringObject detectionCompound structuresGraph structuresGraph-based representationsHier-archical clusteringIndividual objectsObject DetectionObject groupsPosition dataSpatial alignmentStatistical informationStructural characteristicsStructural featureStructural informationTraditional techniquesAlignmentRemote sensingGeologyConference Paper10.1109/IGARSS.2011.6049690
