WebApr 11, 2024 · The Pearson Correlation Coefficient (PCC) is used to evaluate the image quality in the test set which can be expressed as (3) P C C S, S ′ = ∑ ∑ O − O ¯ O ′ − O ′ ¯ ∑ ∑ O − O ¯ 2 ∑ ∑ O ′ − O ′ ¯ 2 where O ¯ and O ′ ¯ denote the mean value of the object and the output of the network, respectively. WebMay 3, 2024 · Two correlations with r = −1 and r = 1 are shown in Figure 1A and B, respectively. The values of −1 and 1 indicate that all observations can be described perfectly using a straight line, which in turn means that if X is known, Y can be determined deterministically and vice versa.
