Schematic view of the proposed method. The intra-layer correlation is computed by the Gram matrix over the activation volumes of a Convolutional Neural Network (CNN). Then the abnormality and the average of the correlation are computed before applying the min-max scaling on both of them. In the end, the two metrics are summed resulting in the predicted image quality score.
