Abstract

Detekcija i usporedba vodenih znakova jednostavan su zadatak za običnog promatrača, no problem automatizacije tog procesa u svijetu filigranologije još uvijek se ne smatra potpuno riješenim. U ovom je radu predstavljena kratka povijest ručne izrade papira i pojave vodenih znakova s ciljem naglašavanja njihovog značaja u cjelokupnom procesu. Opisane su metode i dizajniran računalni program koji na temelju ulazne slike papira s vodenim znakom iz mape testnih slika izdvaja one za koje zaključi da se na njima nalazi isti taj vodeni znak. Kroz rad su postavljeni temelji suradnje s Nacionalnom i sveučilišnom knjižnicom u Zagrebu u svrhu prikupljanja, detekcije i klasifikacije vodenih znakova iz njihove građe.

Abstract (english)

Manual detection and comparison of watermarks on hand-made paper is a relatively simple problem, even for an untrained eye, but when it comes to automating the process, problems arise, hence this task still isn't considered solved in filigranology. This work described a short history of paper making and origin of watermarks with emphasis on their significance in the whole process. The methods were described and a program was designed which, based on an input picture of an old paper sheet with watermark on it, detects images from a database that it considers to contain the same watermark. Through the work the foundation has been laid for future collaboration with National and University Library in Zagreb for the purpose of collecting, detection and classification of watermarks from their literary material.
