摘要
本文应用概率理论分析了中值滤波器的性能。从随机变量的序分布入手,导得了中值滤波器在一般分布情况下的性能参数公式和指数分布及正态分布两种特殊情况下的滤波器性能参数。分析方法和导出的公式对实际应用环境中的中值滤波器的设计和应用具有指导意义。
The probability theory is used to analyse the property of middle-value filters in this paper. By applying the sequence distribution formula of stochastic variables, the property parameter formulae for general distribution are deduced, and the property parameters of exponential distribution and Gauss distribution are also obtained. The method used and the formula deduced are of great value to design and application of the filter.
