摘要:

本文从数学形态学算子与粗糙集中上下近似算子的关系入手,指出了形态学运算膨胀与腐蚀、开与闭分别可视为相似关系下的两对上下近似算子,并构造出新的形态学算子。实现该算子,发现该算子具有良好的性质。

关键词: 粗糙集 相似关系 数学形态学 强膨胀 强腐蚀

Abstract:

This paper starts with the relations between mathematics morphology filter operators and approximation operators, points out that morphological dilate and erode, open and close can be regarded as dual approximation operators in the rough set theory, and presents some new operators. Good qualities are  found of the new operators.

Key words: (rough set, similar relation, mathematical morphology, strong dilation, strong erosion)
