(a)–(d) The original projection image of the gold particle and its noise corrupted images at various levels of salt-and-pepper noise: (a) noise ratio at 0%; (b) noise ratio at 10%; (c) noise ratio at 20%; (d) noise ratio at 40%. (e) The MSE values of the conventional and the proposed methods (red and blue, respectively) are plotted with respect to the noise ratio. The reconstructed image slices are shown in the inset. |
