Rick Chartrand and Brendt Wohlberg, "Total-variation regularization with bound constraints", in Proceedings of IEEE International Conference on Acoustics, Speech, and Signal Processing (ICASSP), (Dallas, TX, USA), doi:10.1109/ICASSP.2010.5494993, pp. 766--769, Mar 2010

Abstract

We present a new algorithm for bound-constrained Total-Variation (TV) regularization that in comparison with its predecessors is simple, fast, and flexible. We use a splitting approach to decouple TV minimization from enforcing the constraints. Consequently, existing TV solvers can be employed with minimal alteration. This also makes the approach straightforward to generalize to any situation where TV can be applied. We consider deblurring of images with Gaussian or salt-and-pepper noise, as well as Abel inversion of radiographs with Poisson noise.
