Median Filter - Worked 1D Example

Worked 1D Example

To demonstrate, using a window size of three with one entry immediately preceding and following each entry, a median filter will be applied to the following simple 1D signal:

x =

So, the median filtered output signal y will be:
y = Median = 2
y = Median = Median = 6
y = Median = Median = 6
y = Median = Median = 3

i.e. y = .

Famous quotes containing the word worked:

    “Imagination of my kind is most caught, most fired, most worked upon by the unfamiliar: I have thriven ... on the changes and chances, the dislocations and ... contrasts which have made up so much of my life.”
