• Threshold enhancement
◦ Remove coverslip – If selected, the edges of the coverslip are not detected as specimen
to be scanned. Depending on the threshold level, it is possible that the edges of the
coverslip are detected as areas to be digitized.

Caution!
It requires lots of time (since it cannot find focus neither on the edges,
nor on specks) to digitize coverslip edges. Select Remove coverslip
function to eliminate those areas.
Warning!
Do NOT use Remove coverslip function on TMA slides! The layout of
TMA slides may mislead the detecting algorithm.
◦ Fill holes inside the scanmap – If selected, the holes inside the specimen will also be
scanned. Often these holes contain small sample objects that otherwise would not be
scanned.
◦ Remove specks – If selected, the scanner does not digitize objects smaller than the
predetermined size. This helps filtering specks and other uninteresting objects out. Set
the maximum size of specks not to be digitized by adjusting the slider.
◦ Dilate mask – Adjust the slider to enlarge or decrease the scanned area. The edge is
extended discretely by 100 µm each time.
