Stationary Wavelet Transform
----------------------------

`Stationary Wavelet Transform (SWT) <http://en.wikipedia.org/wiki/Stationary_wavelet_transform>`_,
also known as *Undecimated wavelet transform* or *Algorithme à trous* is a translation-invariance
modification of the *Discrete Wavelet Transform* that does not decimate coefficients at every
transformation level.
