Abstract
There has recently been considerable interest in applying Total
Variation regularization with an
ℓ1 data fidelity term
to the denoising of images subject to salt and pepper noise,
but the extension of this formulation to more general problems,
such as deconvolution, has received little attention. We
consider this problem, comparing the performance of
ℓ1-TV deconvolution,
computed via our Iteratively Reweighted Norm algorithm, with an
alternative variational approach based on Mumford-Shah
regularization. The
ℓ1-TV deconvolution
method is found to have a significant advantage in
reconstruction quality, with comparable computational cost.
