Fig. 3: Pathologists’ blind evaluation of brightfield Congo-red stain image quality (virtually stained vs. histochemically stained).

A total of 163 image patches are evaluated, each by 3 pathologists. The scores are given for four metrics where their distributions are shown in violin plots in (a). The mean and standard deviation values (as error bars) are plotted for each individual pathologist in part (b). Source data of pathologists’ scores are provided as a Source Data file.
