Abstract(in English)	In this manuscript, I would like to look back on my research related to the nonlinear digital filter which is done since 1990. We could say that the origin of nonlinear filters is the median filter which is introduced by J.W. Tukey in 1974. After that, the nonlinear filter is systemized by "the order statistics filter", "the weighted median filter" and "the stack filter" which contain the median filter. Furthermore, high quality filters which are marge the concept of the nonlinear filter and the linear filter such as "the LI filter" and "the LWOS filter" were proposed. These nonlinear filters were expanded into data-dependent filtering version and fuzzy filtering version in my research. I would like to review of my research related to the data-dependent nonlinear filter and the fuzzy nonlinear filter.
