The noise-resolution tradeoff curves. (a) the noise-resolution tradeoff curves of the insert C4 from the KL-PWLS and SR-NLM algorithms; (b) the noise-resolution tradeoff curves of the insert C4 from the NLM and SR-NLM algorithms; (c) the noise-resolution tradeoff curves of the insert C1 from the KL-PWLS and SR-NLM algorithms; and (d) the noise-resolution tradeoff curves of the insert C1 from the NLM and SR-NLM algorithms. The noise-resolution tradeoff curves shown in (a) and (c) were obtained by varying the penalty parameter β from 100 to 1000 and those shown in (b) and (d) were obtained by varying the scalar parameter τ from 5×10−4 to 1×10−2.
