| 摘 要： | 针对含噪SAR图像的统计特性,提出了一种基于D-S证据理论的SAR图像边缘检测算法。该算法采用非下采样Contourle变换,结合Ratio算法良好的抗噪和恒虚警性能,构建基本置信指派函数。最后对实测的SAR图像进行仿真,仿真结果表明该算法具有良好的抑制斑点效果,并能完整和准确地检测直线边缘,对弱边缘检测也表现良好。

| Abstract: | According to statistical characteristics of SAR images,a new edge detection algorithm based on D-S evidence theory is proposed in this paper.The algorithm combining the advantages of multi-scale,multi-direction and translation invariance for Nonsubsampled Contourlet Transform(NSCT) and performance of good anti-noise and constant false alarm rate(CFAR) for Ratio algorithm.Credibility functions are constructed between NSCT and Ratio to perform information fusion based on D-S evidence theory.The simulation res... |
