The width of urban road is various. Roads with different width have different appearance in an image. Multi-resolution analysis-based method for road extraction was proposed. Firstly, some wide roads in IKONOS multi-spectral imagery were extracted through using level set-based method. While some narrow roads, which are non-salient in 4m multi-spectral imagery, were extracted from 1m fusion imagery. Because the central green belt and some continuously arranged road-side trees can imply a road… CONTINUE READING
