Note(s) : Blind deconvolution is a classical image processing problem which has been investigated
by a large number of researchers over the last four decades. The purpose of this monograph
is not to propose yet another method for blind image restoration. Rather the basic
issue of deconvolvability has been explored from a theoretical view point. Some authors
claim very good results while quite a few claim that blind restoration does not work.
The authors clearly detail when such methods are expected to work and when they will
not. In order to avoid the assumptions needed for convergence analysis in the Fourier
domain, the authors use a general method of convergence analysis used for alternate
minimization based on three point and four point properties of the points in the image
space. The authors prove that all points in the image space satisfy the three point
property and also derive the conditions under which four point property is satisfied.
This provides the conditions under which alternate minimization for blind deconvolution
converges with a quadratic prior. Since the convergence properties depend on the chosen
priors, one should design priors that avoid trivial solutions. Hence, a sparsity based
solution is also provided for blind deconvolution, by using image priors having a
cost that increases with the amount of blur, which is another way to prevent trivial
solutions in joint estimation. This book will be a highly useful resource to the researchers
and academicians in the specific area of blind deconvolution
