Methods

Process(IObservable<Mat>)

Filters frequencies in the input signal using a linear phase filter with the specified design parameters.

public override IObservable<Mat> Process(IObservable<Mat> source)

Parameters

source IObservable<Mat>

A sequence of Mat objects representing the waveform of the signal to filter.

Returns

IObservable<Mat>

A sequence of Mat objects representing the waveform of the filtered signal.

Process(IObservable<double>)

Filters frequencies in the input signal using a linear phase filter with the specified design parameters.

public IObservable<double> Process(IObservable<double> source)

Parameters

source IObservable<double>

A sequence of floating-point numbers representing the waveform of the signal to filter.

Returns

IObservable<double>

A sequence of floating-point numbers representing the waveform of the filtered signal.
