Detailed Description

Filter to apply WMMR-MED filter (weighted majority with minimum range - median) The process first ranks the values within the filter window in numerical order (number of values = N).

The filter then finds a fixed-size subset in which the values are most closely spaced, and calculates a median value from it (WMMR-MED value). The number of values in the subset is (N + 1) / 2. The output value of the filter is a user-controlled weighted average of the input raster value and the WMMR-MED value.
