Comparison between voted overall quality and best detected magnification Distribution of the (human assessment; computer assessment) pairs for 100 WSI with various blurred levels. Human assessment is distributed in three categories: poor/fair/good quality for diagnosis. Computer assessment is distributed in five different magnifications (from 1.25X to 20X): it shows the highest acceptable magnification for a WSI, i.e. the magnification for which the WSI computed quality is sufficient, implying that higher magnifications of this WSI are of insufficient quality. The surface of the disk is proportional to the number of identical pairs. The horizontal bars represent the mean of the highest acceptable magnifications of the computer assessment at each category of human assessment, with vertical bars as their respective standard deviation.
