摘要
提出了一种新的用于抑制散斑噪声的非线性加权均值多方向形态滤波算法.对实际激光雷达图像处理的结果表明,该算法既有效地抑制了激光雷达图像中的散斑噪声,又保持了图像的几何结构.
Abstract
In this paper, a new nonlinear weighted average multidirectional morphological filtering algorithm is proposed to suppress speckle noise. Processing to the images from CO_2 coherent laser radar shows the algorithm can not only preserve the geometrical features of images but also effectively suppress speckle noise in images.
