Results obtained by applying the previously reported methods and the proposed method to the actual LR image shown in Figure 20a. (a) LR image. HR image reconstructed by (b) sinc interpolation, (c) reference [11], (d) reference [27], (e) reference [8], (f) reference [12], (g) reference [28], and (h) the proposed method. The magnification factor is set to eight, and the obtained results are 400 × 400 pixels.
