Project Aims Improve all steps of wm processing Research in recording technology Distributed database Develop and extend an integrated wm processing system EVA2004 Moscow
Starting Situation Database in Vienna of medieval watermarks from manuscripts in Klosterneuburg (Haidinger) Watermark database and processing tools (Victor Karnaukhov) Database of wm of Dutch incunabula (vanThienen) Invention and research of betaradiography in St. Petersburg (Dmitrij Erastov) and image processing (Denis Tsypkin) EVA2004 Moscow
Watermark Recording rubbing beta radiography electron radiography digital camera special illumination multispectral images (infrared) image processing EVA2004 Moscow
Rubbing EVA2004 Moscow
Rubbing EVA2004 Moscow
Rubbing EVA2004 Moscow
Rubbing (poor) image quality depending on quality of paper removal of overlapping text very cheap fast procedure portable equipment scanning of images required EVA2004 Moscow
Beta radiography EVA2004 Moscow
Beta radiography EVA2004 Moscow
Beta radiography EVA2004 Moscow
Beta radiography EVA2004 Moscow
Beta radiography good image quality removal of overlapping text expensive (beta radiography plate, film) long exposure times (up to 8 hours) portable equipment scanning of images required EVA2004 Moscow
Electron radiography film lead foil EVA2004 Moscow
Electron radiography EVA2004 Moscow
Electron radiography EVA2004 Moscow
Electron radiography very good image quality removal of overlapping text very expensive (service, film) short exposure times (250-300 in 4 hours) big equipment, not portable everywhere scanning of images required EVA2004 Moscow
Digital camera State Historical Museum (E. Oukhanova) Tools: 1. Digital camera Olympus C-3030Zoom 2. Slimlight device 3. A scale, a little weight (a piece of marble) Resolution for processing: folio – 170-210 dpi, quarto – 200-250 dpi EVA2004 Moscow
Slimlight 1mm foil electroluminiscence flexible homogenous illumination no heat and ultraviolet radiation EVA2004 Moscow
Digital camera EVA2004 Moscow
Digital camera good image quality, BUT no removal of overlapping text (only by sophisticated software) very cheap (digital camera, illumination) short processing time portable equipment no scanning of images required, no hardcopy EVA2004 Moscow
Watermark Processing preprocessing geometric corrections contrast enhancement standardized quality geometric corrections orientation crop extraction (segmentation) EVA2004 Moscow
Watermark database Databases: libraries, books, types, watermarks, ... Classification of wm into types, subtypes (6 levels) Multilingual (problem of miss. standards) Search for identical wms or variants EVA2004 Moscow
Type/Subtypes EVA2004 Moscow
Watermark database and toolkit EVA2004 Moscow
Results Enlargement and improval of the wm databases and processing systems in TheHague and Vienna Watermark database at the Historical Museum in Moscow Watermark database at the Russian State Library in St. Petersburg Multilingual database (English, German, Russian) Combination of all four watermark databases EVA2004 Moscow
