Figure 20
The selected area marked by the red window in Fig. 17(A) enlarged for Fig. 19 (area [651:951, 701:1001] of [1:2560,1:2560], pixel-value [−1/2560:1/2560]). (A) From the original dataset with 361 projections. (B) Using UDNN-128 and an upscaling factor of 4× (361 projections). (C) Using cubic interpolation (361 projections). Again, the proposed method (panel B) introduces less noise and fewer rotation artefacts. |
