| 摘 要： | 条件平滑滤波是一种非线性滤波。它通过设置阈值,对图像平滑处理进行控制,以便在突出 低频信息的同时,保留有用的边界信息和减少模糊效应,是分类和信息提取前对图像进行预处理 的较好方法。本文介绍了条件平滑滤波方法的原理和算法,以及本方法在S101图像处理系统上 的实现,并以实例阐述了条件平滑滤波的方法在遥感图像处理中的应用。

| Abstract: | The conditional smoothing filter is a nonlinear filter, which can hot only highlights the low frequency information, but also preserves useful edges and compresses blurning effect of smoothing filter by setting a threshold to control the smoothing possess, It is a useful pre-processing method for image classfi cation and information extraction. This paper presented the .principle and algorithm of this method and its implementation in S101 image processing system.Two examples are given to illustrate its application to remote sensing image processing. |
