Results obtained by applying the previously reported methods and the proposed method to the actual LR image shown in Figure 19a: (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.
