基于曲面拟合的SAR图像分维特征提取方法

A Method for SAR Imagery Fractal Feature Based on Curved Surface Fitting

本文对 ＳＡＲ图像的目标统计特性进行了分析，并对原始 ＳＡＲ图像数据采用小波分解进行了乘性噪声抑制，提出了一种用最小二乘法拟合空间曲面的分维特征提取算法，并应用该方法对ＳＡＲ图像数据进行了实验，得到了理想的效果．

In this paper, the statistical properties of SAR imagery is discussed and a method performing pre-processing on the radar image using WT9Wavelet Transform ) and an algorithm for computing the fractal fea- tures are analyzed And,the algorithm is used to L-SAR imagery for the image segmentation It is clear that satisfactory results are obtained.
