| 摘 要： | 中巴资源一号卫星图像中存在比较明显的条带干扰现象。本文利用小波分析的多分辨和局部化性质，根据卫星探测头中探测元的个数，精确地选择小波分解中相应的子图进行处理，针对性强，效果理想。在处理反射层尾现象和保持图像信息方面，该方法优于基于Fourier分析的频域滤波方法。实验表明该方法效果良好。

| Abstract: | The usual method used to smooth strip is filtering in frequency field.Using the multi-scale and localization properties of wavelet,and according to the number of detect-elements of a detector in satellite,an proper sub-image which has good pertinence can be got by wavelet decompose.This method is better than Fourier transform based filtering in frequency field.Experiments with CBERS-1 image have shown that this method is of better result and higher speed. |
