Abstract : In this work, we present a semi-automatic road extraction scheme to detect roads from low resolution satellite imagery. Our approach, we used the a\ trous algorithm to locate and identify roads. Principle component analysis (PCA) is used to combine the detail coefficients. After detecting possible road pixels, we used a graph searching algorithm to draw a final complete road network. We found that our approach leads to an effective method to form the basis of a road detection approach.
