Comparison: bumps signal. (a) Original bumps signal, (b) bumps signal with the addition of white Gaussian, sample size is 2048, input MSE = 0.3, (c) reconstruction with SURE Shrink method MSE = 0.16, (d) reconstructed signal with SSplit (ws= 0.007), MSE = 0.14, (Ψ(t)) is the second derivative of Gaussian function.
