Abstract :
An automatic road extraction method was proposed based on level set and shape metric for sensing digital image. Level set approach is applied for segmenting sensing image. Second order moment is calculated and the road networks are extracted using prior information about geometric shape. Experimental results on real remote sensing images show that this method is efficient in extracting road networks.
