RECONSTRUCTIONS 2/3

Comparaisons des résultats obtenus avec différentes méthodes

Reconstruction sans régularisation

The reconstruction algorithm use a Conjugate Gradient technique to solve the nonlinear system. More informations can be found in the paper [1]. Here are the reconstruction showed step-by-step.

Real part	Imaginary part

Reconstruction avec régularisation de Tikhonov

This regularizing technique removes the noise picks, but the resulting image is oversmoothed. More informations can be found in the paper [2].

Real part	Imaginary part

Reconstruction avec régularisation par préservation des discontinuités

This regularizing technique removes the noise picks, but the resulting image is oversmoothed. More informations can be found in the paper [2].
