Fig. 2

Predictive power of sets of features with \(p \le 0.05\) for H&E staining (top), ERG staining (middle), and PIN-4 staining (bottom). Boxplots of Gini coefficients of features are given specifically for color transforms: Red, Green, Blue, Saturation, Brightness, and od sum. For H&E, additional box-plots of the stain–specific colors Hematoxilin, Eosin, and Residual are plotted. For ERG, additional box-plots of the stain–specific color transforms Hematoxilin, ERG, and Residual are plotted. The predictive power of features varies for the color transforms in each staining
