Signal Processing Filters

Signal processing filters applied to a stream objects.

morphocut.filters.BinomialFilter()

Apply a binomial kernel (e.g. [1,2,1]) to the specified window.

.note:

Only supports centered filters.

morphocut.filters.ExponentialSmoothingFilter()

Smooth value over a stream of objects with exponential decay.

Parameters

• value (RawOrVariable) – Values to smooth.

• alpha (float) – Decaying factor, 0 <= alpha <= 1.

Returns

Variable – Smoothed value.

Formula: out = alpha * value + (1 - alpha) * last_value

morphocut.filters.MaxFilter()

Calculate the maximum inside the specified window.

morphocut.filters.MeanFilter()

Calculate the mean inside the specified window.

morphocut.filters.MedianFilter()

Calculate the median inside the specified window.

morphocut.filters.MinFilter()

Calculate the minimum inside the specified window.
