PyWavelets is a Python wavelet transforms module that includes:

• nD Forward and Inverse Discrete Wavelet Transform (DWT and IDWT)
• 1D and 2D Forward and Inverse Stationary Wavelet Transform (Undecimated Wavelet Transform)
• 1D and 2D Wavelet Packet decomposition and reconstruction
• 1D Continuous Wavelet Tranfsorm
• Computing Approximations of wavelet and scaling functions
• Over 100 built-in wavelet filters and support for custom wavelets
• Single and double precision calculations
• Results compatibility with Matlab Wavelet Toolbox (tm)
