| http://www.w3.org/ns/prov#value | - The optimal data set is obtainedat n = 1, where the upper limit of the normalized image noise is a minimum. (b) L-Curveswith noisy data at different n are plotted to identify the optimal regularization parameter ??.The n = 1 curve is the closest to the origin, which also indicates the advantage of using adata set with n = 1 for image reconstruction.reduced image noise (minimizing the norm of the r
