图8 6%噪声水平下不同降噪方法的视觉对比结果. 从上至下依次给出b=0、b=1 000 s/mm²及b=2 000 s/mm² 条件下的图像，用以反映各方法在不同扩散敏感度下的表现差异

Fig. 8 Visual comparison of different denoising methods at a 6% noise level. From top to bottom, images under conditions of b=0, b=1 000 s/mm², and b=2 000 s/mm² are shown to reflect the performance differences of each method at varying diffusion sensitivities
