The initial implementation was simplified to reduce the number of
local variable. Consequently the parameter data.size was wrong. It was
the size of the fourier spectrum, with hermitian property, instead of
the real space size. This should work.
In addition the PSF is now normalized.
This module add three function to skimage. The `wiener` function is a
simple wiener deconvolution. The `unsupervised_wiener` is a more
sophisticated wiener deconvolution with automatic estimation of
regularisation parameters. The third function is a literal traduction
in python of the rychardson lucy deconvolution of wikipedia.
