Based on Contour Bougie morphology (CB morphology) and generalized multiple structuring elements morphology,a novel series-parallel complex morphological filter was constructed for suppressing the speckle noise in images.Firstly,an omnidirectional multiple structuring element morphology open-Max and close-Min parallel filter was adopted to filter the noise at the cost of minimal loss of image geometrical details,and then a CB morphology open and close operation series filter was used to filter the remaining speckle noise.Thus,it can not only effectively suppress the speckle noise in images but also preserve more geometrical structure features of the images.The results of analysis and simulation prove that the algorithm presented in the paper is efficient.
