PDWT primarily aims at being fast, simple and versatile for an easy integration in a bigger project. For example, the easy interface and thresholding functions make it interesting for sparse regularization of inverse problems.

"WebWavelet transforms are time-frequency transforms employing wavelets. They are similar to Fourier transforms, the difference being that Fourier transforms are localized only in frequency instead of in time and frequency. The main features of PyWavelets are: 1D, 2D and nD Forward and Inverse Discrete Wavelet Transform (DWT and IDWT) " - Opencv wavelet transform
