Self-adaptive Road Extraction Method

YANG Chunhua;  
We present a method of self-adaptive road extraction in this paper, which used the road vector line as a priori knowledge for self-adaptive region expansion. Comparing with the results of manual interpretation and extraction based on e Cognition, the method proposed in this paper had high accuracy and was close to the result of manual interpretation. When inputting the vector data of road network, without the input parameters or human intervention, this method can extract road network adaptively. The robustness of the algorithm is also good. The highway, the urban road and the rural road have the better adaptability.
