PRIMITIVES CHAIN CODE
Lawrence O’Gorman · 1988
The primitives chain code (F‘CC) is an information-prescrving code for the representation of images containing eightconnected lines. PCC is an extension of the Freeman chain code, but in addition to containing chain code connectivity information, PCC also contains branching and junction topology information. That is, these “primitives” describe the most basic level of line features. PCC was developed as a link between the pixel domain and the feature domain for the purpose of facilitating analysis of line images. Since PCC is a compact and feature-based representation, it enables efficient storage and effective analysis for such applications as fingerprint and line drawing analysis.
