Handwritten signatures are typically written with a dark pen (black or blue) on white paper. By analyzing pixel color properties, we can classify pixels into signature strokes and background paper. A threshold value determines where paper ends and pen strokes begin. Pixels matching the paper are given 100% transparency, leaving you with a clean transparent signature vector ready for digital documents.
