一种基于图像分布的SAR图像边缘检测方法
Edge detection algorithm of SAR images based on images distribution
【摘要】 针对合成孔径雷达图像边缘检测,引入了信号幅-频域上的统计多分辨率分析的概念,结合了非极值抑制和双阈值连接两种处理方法,提出一种新的边缘检测算法。实验结果表明,与传统算法比较,新的边缘检测方法显著提高了边缘检测正确率和边缘定位精度。
【Abstract】 A new edge detect algorithm of SAR images is proposed by the combination of non-extremum suppress and two-threshold link and a conception of statistical radiometric multi-resolution analysis in amplitude-frequency field. The simulation results indicate that the algorithm has a wonderful edge-dete ction performance and high accuracy of edge-position.
