  • 摘要:Building extraction and delineation is one of the most salient problems in cartographic features extraction. This paper presents a novel framework for reliable and accurate building extraction from high-resolution color imagery focusing on building boundary delineation and building roof compositional polygon segmentation. Proposed framework consists of three steps. First, anisotropic diffusion and clustering are applied as pre-processing for denoising and color quantization and then building boundary is extracted by active contour driven by edge-flow. Finally, building roof compositional polygons are segmented by JSEG. The framework is tested on a number of buildings and the results are shown. The result shows the completeness and accuracy that this framework can provide for extracting building from a high-resolution color image data set
