Figure 4.
Two reference elbow X ray images are shown on the left labelled Reference M U R A mini H R Number 0002 and Reference M U R A plus H R Number 0026. Each reference image contains a rectangular region marking the area of interest. To the right of each reference image, cropped super-resolution results of the same region are arranged in rows. The methods listed are S R C N N, F S R C N N, S R G A N, E D S R, R C A N, Swin I R, Over Net, S Mixer b, S Mixer t, L B Net, D i V A Net, and Ours. Each method presents a reconstructed elbow joint region corresponding to the highlighted crop. The grid enables direct visual comparison of structural detail across methods for both M U R A mini and M U R A plus high-resolution cases.Visual comparisons for SR on MURA-mini and MURA-plus. The sample No. 0002 from MURA-mini is picked in the first row. The sample No. 0026 in the second row is from MURA-plus
