computes the ni^(th) derivative of data at level i.


computes the derivative at a Gaussian scale of standard deviation σ.


computes several derivatives der1, der2, .

Details and Options

  • DerivativeFilter is a linear filter that computes the derivatives of data based on a spline interpolation model. Regularization with a Gaussian kernel of standard deviation σ (defaults to 0) can be used to reduce susceptibility to noise.
  • The data can be any of the following:
  • listarbitrary-rank numerical array
    tseriestemporal data such as TimeSeries, TemporalData,
    imagearbitrary Image or Image3D object
    audioan Audio object
  • DerivativeFilter operates separately on each level of data.
  • DerivativeFilter[image,] uses the array coordinate system, where the first coordinate runs from the top to the bottom of image, and the second coordinate increases from left to right.
  • DerivativeFilter gives a result with the same dimensions as data.
  • DerivativeFilter can take the following options:
  • InterpolationOrder Automaticinterpolation order up to 9
    Padding "Fixed"padding method
  • With Padding->{pad1,pad2,}, different padding schemes can be used for every dimension of data.
  • The derivative order has to be smaller than the specified interpolation order.
