Reconstruction results
 
Reconstruction with automatic hyperparameter estimation :

(64 x 64) Synthetic image
 

          
Observed image
SNR=15.9 dB
 
 
Reconstructed image
SNR=28.9 dB
=0.25 and =5
Original image
 
 
 
 

(128 x 128) Image extracted from "Nîmes"
 

    
Observed image
SNR=16.7 dB
 
Reconstructed image
SNR=22.8 dB
 
 
Original image
 
=0.49 and =10
These hyperparamètres are used
for the entire image reconstruction
