| 摘要: |
| 本文分析了序统计滤波器的特性, 并提出了它的几个统计特性。给出了输出信号的解析表达。并着重分析了它的联合分布, 从而对输出信号的独立性进行了一定的描述。这为滤波器的设计提供了理论依据。 |

| Abstract: |
| In this paper, several statistic properties of order-statistic fitlters (OSF) have been proposed, and some properties of OSF have been analysised. The well-analytic distribution functions of OSF'output have been given. It is our major work to analyse the joint distributions of OSF'output. The independence of OSF'output has been discribed. All the analysis offers an analytic tool to process the noisy images. |
