英文摘要Road information is fundamental not only in the military field but also common daily living. automatic road extraction from a remote sensing images can provide references for city planning as well as transportation database and map updating. however, owing to the spectral similarity between roads and impervious structures, the current methods solely using spectral characteristics are often ineffective. by contrast, the detailed information discernible from the high-resolution aerial images enables road extraction with spatial texture features. in this study, a knowledge-based method is established and proposed; this method incorporates the spatial texture feature into urban road extraction. the spatial texture feature is initially extracted by the local moran's i, and the derived texture is added to the spectral bands of image for image segmentation. subsequently, features like brightness, standard deviation, rectangularity, aspect ratio, and area are selected to form the hypothesis and verification model based on road knowledge. finally, roads are extracted by applying the hypothesis and verification model and are post-processed based on the mathematical morphology. the newly proposed method is evaluated by conducting two experiments. results show that the completeness, correctness, and quality of the results could reach approximately 94%, 90% and 86% respectively, indicating that the proposed method is effective for urban road extraction.
