Abstract

In order to overcome the disadvantages of linear filters in certain cases of practical interest, a class of nonlinear filters(rank filters) are constructed based on a class of robust estimates, the rank estimates. A subclass of these filters, the limited-degree extended-averaging Wilcoxon filters, is then described as an interesting example of the rank filters with desirable characteristics. The properties of these filters are discussed and the performance of these filters are analyzed for ideal edges and narrow pulses.

몇몇 실제적인 경우에 나타나는 선형 여파기의 단점을 보완하기 위해, robust 추정량의 하나인 순서 추정량에 근본을 둔 비선형 여파기를 구현하였다. 특히 WIlcoxon여파기와 확장 WIlcoxon여파기의 특성을 조사하였고, 이상적인 edge 입력 및 좁은 pulse입력에 대한 이들 여파기의 성능을 분석 검토하였다.
