The document summarizes research using image analysis to match photographs across multiple art archives, including the Frick Art Reference Library Photoarchive and the Frederico Zeri Foundation archive. Running image matching software on over 1.2 million Frick photos and 290,000 Zeri photos revealed new connections within and between the archives. Combining the archives through automated matching discovered over 1,000 new artwork connections that had not previously been found by human researchers. The analysis demonstrates the potential of merging photo archives through computational methods to reveal new relationships and insights.
NYARC 2014: Frick/Zeri Results
- 1. Photo Archive? Image Analysis John Resig March 2014 http://ejohn.org/research/
- 2. Ukiyo-e.org
- 12. Frick Art Reference Library Photoarchive ? Frick Art Reference Library Photoarchive established in 1920. ? Collects photographs of works of art from around the world, including sponsoring own photography. ? Traditionally image analysis has not been applied to photo archives. ? The Frick Photoarchive was interested in exploring image analysis more after seeing? Ukiyo-e.org.
- 13. Test case:Anonymous Italian Art Photographs ? Anonymous Italian Art photographs are small part (~18,000) of over 1.2 million images in the Frick Photoarchive. ? Very few color photographs (makes most image analysis dif?cult, good test case). ? Analysis was performed by myself in collaboration with the Frick Photoarchive.
- 14. Digital Anonymous Italian Art ? Early digitization project. ? At the time there was no in-house digital lab at the Frick Photoarchive. ? Digitization self-funded and executed by an outside institution. ? When new images were added they were not “merged” -- too hard with no attribution.
- 15. Image Analysis ? I wrote custom software to automate matches using MatchEngine (a TinEye service). ? Extremely effective image matching technology. ? Matches same images and portions of images, even in black-and-white.
