PyWavelets is very easy to start with and use, and currently is capable of:

  • 1D and 2D Forward and Inverse Discrete Wavelet Transform (DWT and IDWT)
  • 1D and 2D Stationary Wavelet Transform (Undecimated Wavelet Transform)
  • 1D and 2D Wavelet Packet decomposition and reconstruction
  • Approximating wavelet and scaling functions
  • Over seventy built-in wavelet filters and custom wavelets supported
  • Single and double precision calculations
  • Results compatibility with Matlab Wavelet Toolbox (tm)
Build Status

Requirements

PyWavelets is a package for the Python programming language. It requires:
