Recognition process and tracking fibrous substrates and applications of said method in particular in the field of computer

摘要

Acceptance procedure of a candidate fibrous medium, paper, cardboard or nonwoven, fibrous comosoporte authentic, comprising the following steps: - generating at least an authentic digital signature from a structural characteristic extracted from unazona reference a fibrous support qualified authentic, said digital signature representing the estructurafibrosa of the reference area, and record this on a support digital data, - generating a candidate digital signature from a structural characteristic extracted from a zone dereference the support fibrous candidate, said digital signature representing the fibrous structure of dereferencing area, - comparison of the candidate digital signature with at least one of the authentic digital signatures previamentealmacenadas, so that a positive or negative acceptance fibrosocandidato support decision is issued, It characterized by that: - the feature is ructural the fibrous support candidate and (the) support (s) fibrous (s) authentic (s) seobtiene examining a volume of the support, - the determined comparison, according to a statistical method, a similarity between the signature digitalcandidata and digital signature authentic, and compares the index of similarity with an acceptance threshold given selected to enable issuing a positive acceptance decision in cases where lafirma digital candidate does not match exactly to the authentic digital signature which it compares.
