MedianFilter

streaming mode | Filters category

Inputs

  • array (vector_real) - the input array (must be non-empty)

Outputs

  • filteredArray (vector_real) - the median-filtered input array

Parameters

  • kernelSize (integer ∈ [1, ∞), default = 11) :
    scalar giving the size of the median filter window. Must be odd

Description

This algorithm computes the median filtered version of the input signal giving the kernel size as detailed in [1].
