Class OneEuroFilter

constructor

• new OneEuroFilter(freq, minCutOff?, beta?, dCutOff?): OneEuroFilter

• Create a new OneEuroFilter

  Parameters

  • freq: number

    An estimate of the frequency in Hz of the signal (> 0), if timestamps are not available.
  • minCutOff: number = 1.0

    Min cutoff frequency in Hz (> 0). Lower values allow to remove more jitter.
  • beta: number = 0.0

    Parameter to reduce latency (> 0). Higher values make the filter react faster to changes.
  • dCutOff: number = 1.0

    Used to filter the derivates. 1 Hz by default. Change this parameter if you know what you are doing.
