摘要

对称加权阈值滤波器是对秩阶滤波器的一种推广。本文研究了迭代对称加权阈值滤波器对有界序列的滤波行为，证明了偶指数迭代序列和奇指数迭代序列都是收敛的，并且这些极限序列要么是这些滤波器的根，要么是它们的循环序列。

Filtering behavior of iterated symmetric weighted threshold filters for bounded sequences

The symmetric weighted threshold filters is a generalization of rank order filters. In this paper, we study filtering behavior of iterated symmetric weighted threshold filters for bounded sequences and prove that iterated sequences with even index as well as iterated sequences with odd index both converge, and these limiting sequences are either roots of these filters or their recurrent sequences.
