Center line vectorization techniques

The Information contained In a picture Is represented by broken lines following either the center-lines or the outlines of the drawings. These techniques are commonly referred to as vectorlzatlon techniques as they mainly consist of position vectors of the corner points of polygon lines. 

In the following, we concentrated on the characteristic features and efficiency data of commercial systems and system components for vectorizing binary Images. The systems were tested during visits to various US and European institutions. Principally one can differentiate between two main vectorization techniques center line and outline representation.
