Methods

Process(IObservable<Mat>)

Convolves the input signal with a finite-impulse response filter kernel.

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<Point2f>)

Convolves the input position signal with a finite-impulse response filter kernel.

public IObservable<Point2f> Process(IObservable<Point2f> source)

Parameters

source IObservable<Point2f>

A sequence of 2D points representing the position signal to filter.

Returns

IObservable<Point2f>

A sequence of 2D points representing the filtered position signal.

Process(IObservable<double>)

Convolves the input signal with a finite-impulse response filter kernel.

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.
