摘要
近几年，我国地面站接收处理的美国陆地卫星ＴＭ６波段图像经常出现横纹条带状噪声。本文分析了噪声的特点及产生的原因，并基于统计中直方图配准的思想，设计了消除噪声的方法，使图像上每一行数据与其条带邻域内的数据具有相同的直方图分布且均值相等。最后，介绍了此方法的实际应用例子。
In recent years horizontal striped noise often occurred in Landsat TM Band 6 imageryacquired and processed by Remote Sensing Satellite Ground Station of China. This paperhas analyzed the characteristics of striped noise and the cause of noise producing. Based onthe idea of histogram matching in statistics,we have designed an algorithm for eliminatingthe striped noise.It makes the data between any line and its striped neighborhood on theimagery have similar probability distribution and equal means. Finally,some applicationexamples of this algorithm were introduced in this paper.
