一类多结构元素并行复合形态滤波器

基于数学形态学中的开－闭和闭－开运算，采用多结构元素，构造了一类并行复合形态滤波器。这类滤波器具有移不变性、递增性、对偶性和幂等性等重要性质，它不仅可以有效地抑制图象中的噪声，而且较好地保持图象的几何结构特征。计算机模拟结果证实了滤波算法的有效性。

A Class of Parallel Complex Morphological Filterswith Multiple Structuring Elements

Based on the open-closing and close-opening operators in mathematical morphology, a class of parallel complex morphological filters is constructed by using multiple structuring ele- ments . These filters possess some important properties such as translation invariance, increasing, duality and idempotence. 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.
