Graph of the the number of control points and the fidelity-to-data term with respect to the sparsity parameter γsp with data of Fig. 2. There is a whole range γsp ∈]0, 4] for which the number of control points can be divided by 2.4 to 5.3 (from 27 to 12 compared to the initial 64 control points) for an almost constant atlas sharpness.
