4.3. Feedback vs Feedforward

The impact of feedback on Set5 with scale factor ×4

4.4. Curriculum Learning

The investigation of curriculum learning (CL) on BD and DN degradation models with scale factor ×4. The average PSNR values are evaluated on Set5

5. SOTA Comparison

5.1. Network Parameters

PSNR Against network parameters

5.2. Results with BI degradation model

Average PSNR/SSIM values for scale factors ×2, ×3 and ×4 with BI degradation model. The best performance is shown in red and the second best performance is shown in blue.
Visual results of BI degradation model with scale factor ×4.

5.3. Results with BD and DN degradation model

Average PSNR/SSIM values for scale factors ×2, ×3 and ×4 with BD and DN degradation model. The best performance is shown in red and the second best performance is shown in blue.
Visual results of BD and DN degradation model with scale factor ×3.
