Figure 6

Comparisons of the proposed method with the wavelet-based method. (a) The reference signal, (b) the simulated noise for baseline wander and partial motion artifacts, (c) the simulated noisy signal with baseline wander and partial motion noise, (d) the simulated noisy signal with multinoise, (e) the denoised signal of Figure 6(c) by using the wavelet-based method, (f) the denoised signal of Figure 6(d) by using the wavelet-based method, (g) the denoised signal of Figure 6(c) by using the proposed method, and (h) the denoised signal of Figure 6(d) by using the wavelet-based method.
