WP 2 – Repertories Concordance

Demands:– Matching of Printed Piccard and Piccard-Online– Piccard-Online based on Piccard-collection with

92.000 watermarks– Printed Piccard: 52.000 watermarks– Proof of conformity – Amount of similar watermarks clear, yet

Aim:– One Application: Piccard-Online for Bernstein-

Workspace

WP 2 – Repertories Concordance

Cooperation partners: KSBM, DUT and LABW Meetings in Stuttgart

WP 2 – Repertories Concordance

Assumption for Mapping – Digitized Printed Piccard– Creating metadata– Isolation watermarks– Measuring watermarks– Comparison of watermarks– Elimination of duplicates – Integration of remaining watermarks in Piccard-

Online

WP 2 – Repertories Concordance

Approach: – Preliminary work done concerning digitizing and

metadata– First meeting concerning technical realisation:

Stuttgart in October 2007– Presentation of tools based on Matlab– Partner: KSBM, DUT, LABW– Evaluation of tools– Second meeting in Stuttgart March 2008– Partner: LABW and KSBM

WP 2 – Repertories Concordance

Difficulties:– First Problem of Matlab: Licensing– Different licence educational institution and

commercial/not profit institutions– LABW was not excepted as an educational

institution– Testing of “Printed Piccard Scissors” was done

by KSBM (reason just ¼ of licensing costs as for LABW)

– Second Problem: functionality of tools need to be modified

WP 2 – Repertories Concordance

Results:– Isolation of watermarks in digitized Printed

Piccard is finished– Isolation of watermarks in Piccard-Online

-> evaluation of “Piccard-Online Scissors” based motif “Balance”-> Basis for the modification of isolation and cutting tool as well comparing tool

– Not finished yet, work still in progress
