MSGF-Net: a multi-scale spectral-gradient fusion network for perceptual image quality assessment of low-dose CT
The proposed MSGF-Net embeds a Hybrid Gradient-Frequency Attention Module (HG-FAM) within the residual bottlenecks to achieve dual-domain synergistic perception of global spectral energy and spatial gradient details and significantly outperforms existing main-stream methodologies.
