摘要
针对合成孔径雷达（SAR）图像的特点，利用小波变换的高频分量能反映边沿细节的特性，提出了一种结合小波变换、中值滤波、自适应门限判决和微分梯度算子的边沿检测方法。实验结果表明，该方法具有良好的边沿检测效果和稳定性。
Based on the analysis of the characteristics of synthetic aperture radar (SAR) images, this paper puts forward a combined method for edge detection of SAR images, which is composed of wavelet transform, median filtef, adaptive thresholding and differential gradient operator.The experimental results show the effectiveness and stability of the method.
