Speckle Noise Suppressing Based on a Generalized Parallel Weighted-Average Multidirectional Morphological Filtering Algorithm

In this paper, a generalized parallel weighted-average multidirectional morphological filtering algorithm is presented to suppressing speckle noise. Simulation shows the algorithm can not only effectively suppress speckle noise but also preserve the geometrical features of images. Through comparison, it is proved that the algorithm is superior to F. Sara algorithm.
