Misrecovery

In the bottom graph, the percentage of misrecoveries by RMSD, BMS, and those common to both are plotted for each of the six bins of parameter sets.

My first point is that perceptual misrecovery is not necessary there.

To take just the most salient instance, the letters or other elements of such systems owe their shapes to a number of quite distinct factors: to physical factors (whether they're set down with a brush or a pen, for instance); to cognitive factors (how they have been affected by human misrecollection and misrecovery); to perceptual factors (how they have been kept distinguishable); and even to esthetic factors (how they fit, when they assumed their final shapes, the cultural values of the time).
