Road extraction from high-resolution remote sensing images with spatial continuity

A new road extraction algorithm model-RESC (road extraction of spatial continuity) based on the spatial continuity is proposed. It is based on road characteristics of continuous distribution in remote sensing image and adjacent pixel have prior information of spatial autocorrelation, and does not need beforehand offer seed, so it have most automated. The high resolution multi-spectral image and pan remote sensing image were chosen to prove that the method of this study is promising.
