<FONT face=Verdana>Road detection is an important task of remote sensing images processing.With the feature of combining picture and spectrum
hyperspectral images present new useful information resource for road detection.With the requirement of remote sensing road detection
a new method for road detection and extraction based on hypersp<FONT face=Verdana>ectral images is proposed.Firstly
independent component analysis and linear mixture model are used to unsupervised unmix the hyperspectral images
and the unmixed independent component including road information is obtained.Then
the road detection and extraction is achieved by means of ratio operator and Hough transform.The results from simulation experiments demonstrate the validity of the proposed method.
