摘　　要：本文在研究SAR影像地物边缘特征和灰度直方图分布规律的基础上,利用方向可调滤波器提取了边缘,并利用多尺度小波融合算法对提取的边缘进行了融合。实验证明,本方法在保持边缘连续性和准确性上取得了较为理想的结果。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.
