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.
