(a) Comparison data between micro-CT and noisy virtual grayscale histograms. The micro-CT histogram comes from the volume dataset obtained experimentally. The virtual images had a kernel size of 1 for blur, a Gaussian noise with \(\mu =0\) and \(\sigma =4\), a Poisson noise with \(k=120\) and \(\lambda =(600,1120,600)\). (b) Evaluation metrics comparing micro-CT and noisy virtual images. All metrics are comprised between 0 and 1 with 1 the best match for Correlation and Intersection while 0 is the best match for Bhattacharyya distance.
