Developing Image Processing Meta-Algorithms with Data Mining of Multiple Metrics

Figure 2

Heat map representation of the correlation matrix for the table of metric values for the 186 variants of input image E4863S4I, with metrics clustered into a hierarchy by rough similarity. The nine last metrics are consistent in the sense that they are highly correlated, with all pairwise correlation values above 0.644. There is nontrivial disagreement between these nine and the edi (Entropy of Difference of Intensities) and woo (Woods) metrics—also shown in Figure 1.
