Comparison of different de-noising methods for Blocks signal (blue: original signal, red: reconstructed signal). (a) Noisy signal with SNR =16.91 dB. (b) Cycle-spinning de-noising. (c) Wavelet footprints de-noising. (d) Wavelet footprints de-noising with oracle. (e) Direct method de-noising with oracle. (f) IPRM de-noising.
