Four data smoothing methods(moving window averaging,moving window weighted averaging,moving window median filtering and moving window robust averaging) are described in this paper.

Optimum design of weighted median filters based on genetic algorithms;

Effective adaptive weighted median filter algorithm

The main characters of this dissertation are as follows:(1)Traditional weighted median filter model is formed based on single dimension signal processing.

An algorithm called adaptive weighted median filter algorithm based on similarity function is proposed by the writer of this article.

The ideas of the directional filtering and the weighted median filtering are combined with each other to construct the ADWM filter model, which is a highly nonlinear image smoothing and enhancement technique.
