A piecewise constant levelset approach for semi-blind deconvolution: Application to barcode decoding
Adriano De Cezaro, Eduardo Hafemann, Antonio Leitão
We consider a semi-blind deconvolution problem arising in the decoding of blurred linear barcodes. Building on the Piecewise Constant Level Set (PCLS) framework introduced in [De\,…

On inertial Levenberg-Marquardt type methods for solving nonlinear ill-posed operator equations
Antonio Leitão, Joel C. Rabelo, Dirk A. Lorenz +1
In these notes we propose and analyze an inertial type method for obtaining stable approximate solutions to nonlinear ill-posed operator equations. The method is based on the Leven…

On inertial iterated Tikhonov methods for solving ill-posed problems
Joel C. Rabelo, Antonio Leitão, Alexandre L. Madureira
In this manuscript we propose and analyze an implicit two-point type method (or inertial method) for obtaining stable approximate solutions to linear ill-posed operator equations.…
