ABSTRACT:
This technique involves digitally filtering data by determining the median of data values instead of mean or some other algebraic combination. It is unique in that the data used for the median calculation utilizes previous as well as the new data. This filter structure can be used in both time domain and spatial domain. Also, the filter size can easily be varied to permit adapting its size to system gain.
