Pipeline overview. High-magnification images are taken from holes in medium-magnification images, which come from squares in low-magnification images. (a) Ptolemy detects, crops and then classifies squares in low-magnification images, which have a pixel size of approximately 200–500 nm pixel−1. (b) Next, Ptolemy detects, crops and then classifies holes in subsequent medium-magnification images, which have a pixel size of approximately 10–100 nm pixel−1.
