Just a couple technical notes:
1. The article states "the operation which is opposite to convolution is equivalent to division in the frequency domain" which is not correct. 2. "Deconvolution" has no mathematical definition (as implied by that quote), it is the name of various algorithmic approaches used in signals processing. 3. Finally, the Wiener filter is not deconvolution, it is just a filter.
Nonetheless, a great article, with great illustrations.
