MaxFilter¶

standard mode | Filters category

Inputs¶

signal (vector_real) - signal to be filtered

Outputs¶

signal (vector_real) - filtered output

Parameters¶

causal (bool ∈ {true, false}, default = true) :
use casual filter (window is behind current element otherwise it is centered around)

width (integer ∈ [2, ∞), default = 3) :
the window size, even size is auto-resized to the next odd value in the non-casual case

Description¶

This algorithm implements a maximum filter for 1d signal using van Herk/Gil-Werman (HGW) algorithm.
