| 摘 要： | 从遥感影像条纹噪声的周期性特征入手,利用图像的频谱图对图像中条纹噪声的频率分布进行分析,并使用巴特沃斯带阻滤波器对条纹噪声进行消除.实验结果表明,该方法能有效抑制条纹噪声,并能保留图像边缘信息.通过对条纹噪声分析发现中巴资源卫星-02星CCD图像存在4种条纹类型.

| Abstract: | Starting with the periodicity of striping noise of remote sensing image,the paper analyzes frequency distribution of striping noise using image spectrogram and eliminates the striping noise by the Butterworth band elimination filter.The study result shows that the method can not only effectively bate striping noise,but also retain image's edge information.Four types of strping noise can be found from the CBERS-02 satellite CCD image after analysing the striping noise. |
