Table 3.

Results of statistical tests between CAE and other denoising methods.

Visual assessment BM3D25 vs CAE BM3D20 vs CAE LNLM0.03 vs CAE LNLM0.02 vs CAE
streak artifact 0.0003491 0.0003212 0.0003615 0.0003098
noise other than streak artifact 0.0004935 0.0004779 0.0002950 0.0002054
visualization of vessel 0.01785 0.02452 0.003091 0.01356
overall image quality 0.02474 0.07272 0.001622 0.001326

Note: The number is the p-value obtained with Mann-Whitney U test. Except the overall image quality between BM3D20 and CAE, the p-values are less than 0.05. Abbreviation: BM3D25, BM3D with the parameter of sigma = 25; BM3D20, BM3D with the parameter of sigma = 20; CAE, convolutional auto-encoder; LNLM, large-scale nonlocal means; LNLM0.03, LNLM with the parameter h = 0.03; LNLM0.02, LNLM with the parameter of h = 0.02.
