| 摘 要： | QuickBird高空间分辨率遥感影像已在各个领域得到了广泛的应用,然而其在获取和传输的过程中通常会受到噪声,特别是脉冲噪声的污染,从而影响了其后续应用。为此,提出了一种基于改进中值滤波的遥感影像中脉冲噪声的检测和滤除算法。首先利用一维拉普拉斯卷积核和扩张函数检测图像中的噪声像素;然后利用向量中值滤波（Vector Median Filter,VMF）对检测到的噪声像素进行恢复。实验结果表明,相对于其它几种噪声滤除算法,所提出的算法取得了较好的噪声滤除效果。

| Abstract: | QuickBird remote sensing image with high spatial resolution has been used in many fields.However,the image is frequently corrupted by noises,especially by the impulsive noise during the process of acquisition and transmission,so as to affects its successive applications.The purpose of this study is to present a method for detecting and removing the impulsive noise from QuickBird remote sensing image based on modified median filter.At the first stage,one-dimensional Laplacian operators and augmentation funct... |
