The libdwt is a cross-platform wavelet transform library with a focus on images and high performance.
The transform is accelerated using SIMD extensions and threads.
Two-dimensional transform can be computed in a single-loop (cache friendly).
The Wavelet Toolbox provides functions and tools for experiments with signals and images.
The toolbox is able to transform FIR filters into lifting scheme.
The toolbox further provides functions to denoise and compress signals and images.
It is also possible to add custom wavelet filters.

PyWavelets is free and open source wavelet transform library.
The library supports real and complex calculations with single and double precision.
Its results are compatible with MATLAB Wavelet Toolbox.
Custom wavelets are also supported.
