摘　　要：本文在层叠滤波器一般性理论基础上,对自对偶层叠滤波器的输出分布进行了研究。结果表明:自对偶层叠滤波器的输出在中值意义上是统计无偏的,并且给出了自对偶层叠滤波器输出分布的一种表达式。The output distribution of self-dual stack filters are studied based on the general theory of stack filter. The results show that self-dual stack filters are statistically unbiased in the sense of median, and an expression of self-dual stack filters can be concluded on output distribution.
