Figure 2: An example piecewise smooth signal of length 1024 and its reconstructions from 300 random measurements using OMP, TOMP, UDT-OMP. (a) Original signal. (b) OMP reconstructed signal, SNR = 27.63 dB. (c) TOMP reconstructed signal, SNR = 34.57 dB. (d) UDT-OMP reconstructed signal, SNR = 39.62 dB.
