“…The discussion on how to choose the appropriate α E , α TV , and β is out of the scope of this paper and thus we choose the optimal one, i.e., the one which gives the highest value of SNR among some tested ones. For a discussion on how to select the regularization parameter for the TV regularization see, e.g., [34,28,31,14,17,19,26,13,32,33]. Moreover, for a discussion on multiparameter selection see, e.g., [20].…”
