| Abstract: | Based on the analysis of the feature of edges and the distribution law of gray histogram of SAR image, the edges are extracted by the method of steerable filters. Then, the extracted edges are fused by the way of multi-scale wavelet fusion. Experiment indicates that the new method is perfect in keeping the continuity and spatial veracity of edges. |
