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 the Choice of the Tikhonov Regularization Parameter and the Discretization Level: A Discrepancy-Based Strategy
Vinicius Albani, Adriano De Cezaro, Jorge P. Zubelli
We address the classical issue of appropriate choice of the regularization and discretization level for the Tikhonov regularization of an inverse problem with imperfectly measured…
Convex Regularization of Local Volatility Estimation in a Discrete Setting
Vinicius V. L. Albani, Adriano De Cezaro, Jorge Passamani Zubelli
We apply convex regularization techniques to the problem of calibrating the local volatility surface model of Dupire taking into account the practical requirement of discrete grids…
Regularization approaches for quantitative photoacoustic tomography using the radiative transfer equation
Adriano De Cezaro, Fabiana Travessini De Cezaro
Quantitative Photoacoustic tomography (QPAT) is an emerging medical imaging modality which offers the possibility of combining the high resolution of the acoustic waves and large c…
Uniqueness and regularization for unknown spacewise lower-order coefficient and source for the heat type equation
Adriano De Cezaro, Fabiana Travessini De Cezaro
In this contribution we show sufficient conditions for simultaneous unique identification of unknown spacewise coefficients and heat source in a parabolic partial differential equa…
A note on uniqueness in the identification of a spacewise dependent source and diffusion coefficient for the heat equation
Adriano De Cezaro, B. Tomas Johansson
We investigate uniqueness in the inverse problem of reconstructing simultaneously a spacewise conductivity function and a heat source in the parabolic heat equation from the usual…
