medianFilter {FBN}

1D Median Filter

Description

1-dimensinal median filter with a specified windowSize of the inputData

Usage

medianFilter(inputData, windowSize)
medianFilter(inputData = NULL, windowSize = 3)

Arguments

inputData

The vector of values to be filtered

windowSize

The half-size of the filtering window (default windowSize = 3)

Details

Classical implementation of a median filter, using a sliding window. By default, the half-size of the sliding window is set to 3 unless otherwise specified.

Value

The output data has the same size of the input data. If the window half-size is smaller or equal to 1, then the input data is passed directly to the output data.

Examples

x <- medianFilter(c(0, 0, 0, 1, 1, 1, 0, 0, 1, 0))
x <- medianFilter(c(0, 0, 0, 1, 0, 0, 0, 0, 1, 0), windowSize = 5)
