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
A new nonlinear weighted mean multi-directional morphological filtering algorithm for suppressing speckle noise is proposed. The results of the actual lidar image processing show that the algorithm not only effectively restrain the speckle noise in the lidar image, but also keep the geometric structure of the image
