摘要: 本文基于數(shù)學(xué)形態(tài)學(xué)中的廣義形態(tài)開(kāi)-閉和閉-開(kāi)運(yùn)算,采用多結(jié)構(gòu)元素,構(gòu)造了一類并行復(fù)合形態(tài)濾波器。這類濾波器具有平移不變性、遞增性、對(duì)偶性和冪等性等重要性質(zhì),并遵守閾值疊加準(zhǔn)則,不僅可以有效地抑制圖象中的噪聲,而且較好地保持了圖象的幾何結(jié)構(gòu)特征。計(jì)算機(jī)模擬結(jié)果證實(shí)了濾波算法的有效性.Abstract: Based on the generalized open-closing and close-opening operations in mathematical morphology, a class of generalized parallel complex morphological filters is constructed by using multiple structuring elements in this paper. These filters possess some important properties such as translation invariance, increasing, duality and idempotence and obey the threshold superposition rule. They can not only effeciently suppress noise in images but also preserve the geometrical features of images. The results of computer simulation show that the new filtering method is quite effective.
