Research on BOLD-fMRI Data Denoising Based on Bayesian Estimation and Adaptive Wavelet Threshold

Figure 1

(a) When the SNR is high, the Rician distribution is close to the Gaussian distribution. (b) When the SNR is very low, the Rician distribution is close to the Rayleigh distribution. (c) When the SNR is medium, the Rician distribution is shown in the figure.
