Figure 7.
Panel A is a line chart with vertical axis labelled P S N R per decibel and horizontal axis labelled Epoch from 100 to 700. Three curves are shown. Ours increases from about 30.25 to about 30.42. Transformer and C N N increases from about 29.78 to about 30.17. Only Transformer increases from about 29.15 to about 29.64. Panel B is a scatter plot comparing H R and Ours M U R A mini x 4. Most points cluster around x between 0.1 and 0.3 and y between 0.45 and 0.6. A smaller group appears around x between 0.25 and 0.4 and y between 0.1 and 0.35. A few points lie near x above 0.8 and y above 0.75. Panel C is a scatter plot comparing H R and Ours M U R A mini x 2. Most points cluster around x between 0.1 and 0.3 and y between 0.45 and 0.6. A secondary cluster appears around x between 0.25 and 0.4 and y between 0.1 and 0.35. A few points are located near x above 0.8 and y above 0.75. Legends identify H R and Ours in both scatter plots.From left to right: (a) PSNR performance with different backbone networks on the MURA-mini data set at scaling factor.
