中文摘要：

针对资源一号02C影像条带噪声的去除,提出了一种改进的矩匹配方法。该方法以移动窗口的方式对大范围卫星影像数据进行分段处理,并根据窗口内影像的信息量,自适应地确定窗口大小,且在参考值获取时引入更合理的高斯加权均值。实验表明,与现有矩匹配方法相比,本文方法在取得良好去噪效果的同时,还具有自动化程度高、灰度失真小等优点。

英文摘要：

CBERS-02 Csatellite images are widely used in the fields of resource investigation,environment protection,and agricultural research,however,the tripe noise is a widespread problem which cannot be ignored.Moment Matching is often used by assuming that the mean and standard deviation of the data acquired by each detector are identical,but traditional methods may cause blurring and ringing artifacts due to the strong assumption of subdetectors viewing the same scene.This paper proposes an improved algorithm for Moment Matching to remove stripe noise in CBERS-02 Cimages.A moving-window which can be resized adaptively is used to deal with a wide range satellite images and the size of the window will depend on the amount of information within it.At the same time,Gaussian weighted method is used to obtain the reference value of column averages and variances.Finally,the stripe noise will be removed with the moving-window from left to right.Experimental results show that the improved method,qualitatively and quantitatively compared with traditional Moment Matching methods,is more effective in eliminating strip noise and avoiding information distortion.Besides,the improved method is computationally efficient and automatic,which can meet the needs of auto production of massive satellite imagery.
