| 摘 要： | 本文介绍一种消除陆地卫星TM夜间图像上干扰条带的滤波方法。该方法的核心是用中位数判 错法首先判出干扰条带的位置,然后对原始图像上构成干扰条带的噪声点作二维空间域平滑滤波。 这种滤波方法不仅能消除干扰条带,而且能保存原始图像上的有用信息。通过滤波处理获得了较 满意的图像。

| Abstract: | It is necessary to remove the interferential stripes distributed on the TM6 night images, when we use them for thermal infrared investigation. A new method, "destripes filter" is introduced in this paper. The Key points of the method are to determine the position of these stripes by means of "median value" and to conduct a 2-dimensional smooth filter to delete the noise points which formed the stripes on the original images. It was proven in a thermal infrared detection and investigation of underground coal fire that the method could keep the original information better and make new satisfying images. |
