(a) The first frame of original table tennis sequence with a red rectangle marking the region to be magnified. (b) Magnified region in the original frame. SSIM maps of the reconstructed images by (c) ELA, (d) EELA, (e) DSWVC, (f) DOI, (g) NEDD, (h) LCID, (i) MELA, (j) FDD, (k) LABI, (l) EMD, (m) EPD, (n) FDED, (o) CAD, and (p) DCAD. Note that since the brighter SSIM map indicates that the image is more similar to the original, we can say that the proposed method provides the most similar image to the original, especially near the edge of table.
