Determine the Wavelet Type

We distinguish five types of wavelets:

  1. Orthogonal wavelets with FIR filters

    These wavelets can be defined through the scaling filter w. Predefined families of such wavelets include: Haar, Daubechies, Coiflets, and Symlets.

  1. Biorthogonal wavelets with FIR filters

    These wavelets can be defined through the two scaling filters wr and wd, for reconstruction and decomposition respectively. The BiorSplines wavelet family is a predefined family of this type.

  1. Orthogonal wavelets without FIR filter, but with scale function

    These wavelets can be defined through the definition of the wavelet function and the scaling function. The Meyer wavelet family is a predefined family of this type.

  1. Wavelets without FIR filter and without scale function

    These wavelets can be defined through the definition of the wavelet function. Predefined families of such wavelets include: Morlet and Mexican_hat.

  1. Complex wavelets without FIR filter and without scale function

    These wavelets can be defined through the definition of the wavelet function. Predefined families of such wavelets include: Complex Gaussian and Shannon.
