Reconstruction of a polystyrene square cylinder
Reconstruction without any regularization (left)
The reconstruction algorithm use a Conjugate Gradient technique to
solve the nonlinear system. More informations can be found in the
paper [1, 4,
Reconstruction with Tikhonov regularization (middle)
This regularizing technique removes the noise picks, but the resulting
image is oversmoothed.
Reconstruction with edge-preserving regularization (right)
This regularizing technique developped in our team smoothes the homogeneous
areas of the image while preserving its edges.
