摘要：An efficient statistical algorithm of automatic extracting road from SAR images is devised in this paper. First, an feature detecting operator is used to find the road candidate. Then another smaller operator which calculating the homogenous statistic of locate region is applied to reduce the false alarm and smooth the road edge. Finally, the road linear features are extracted by fusing the results of these two operators, and a phase grouping method is used to combine the road linear features. We apply this algorithm to a RadarSat image to illustrate the accuracy and efficiency, and the performance is satisfied
