Abstract�� The roof of the building in aerial image is generally rectangle or parallelogram. It makes a significance sense to extract the rectangle accurately and fast, either in military aspect or in civilian aspect.A method based on fussy decision-making for extraction of rectangular buildings from the aerial images was proposed. Firstly, the presumed rectangular space was generated via line feature, which was resulted from beeline-extraction of the aerial image. Then, the support evidences which were get from the image were combined by fussy mathematic method in order to obtain decision-making information.Finally, the generated rectangle was selected and validated according to the decision-making information. This arithmetic uses the non-fixed threshold value to select the supporting evidences to improve the validity. The results of performance assessment also possess the robustness and high extraction rate of the approach developed.
Keywords�� rectangle building   perceptual grouping   fussy decision-making   threshold
