Skeleton dots

Dot removal, a part of algorithm transparency, is the first filter applied to traced skeleton before pore removal. Dots are skeleton minutiae with no ridges (or valleys in valley skeleton) attached to them.

Visualization

Visualization of skeleton after dot removal was constructed by comparing this stage's CBOR and binary data to traced skeleton data. Visualization itself is not part of transparency data.

Format

Format is identical to traced skeleton.
