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.

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].
