Fig. 4

Qualitative comparison of transverse CT image N284 processed using various denoising algorithms: (a) LDCT input, (b) NDCT ground truth, (c) WDPL-GAN, (d) WC-SNR, (e) TOD-Net, (f) RCN-FTV, (g) WSL, and (h) the proposed method. Enlarged views of the red-marked regions of interest (ROIs) are presented below each image for detailed visual inspection. Blue and red arrows indicate bone structures, while yellow arrows highlight smaller anatomical features.
