2012 / CLiP Matching Project launched by Rick Johnson (Cornell)
in collaboration with the Morgan Library & Museum.
2013 / First conference
chain line spacing and angle sequences at ``New Directions
in the Study of Rembrandt and His Circle'' at Herstmonceux Castle.
2013 / The Morgan Library and Museum,
the Rijksmuseum, and the Metropolitan Museum of Art
agree to provide a database in support of
algorithm development composed of dozens of beta-radiographs
of prints by Rembrandt selected to include images of papers
made with the same mold.
2014 / A dataset assembled by the CLiP Project of
129 scanned beta-radiographs
of prints in the collections of the Morgan Library & Museum and
the Metropolitan Museum of Art is made available
Netherlands Insitute for Art History (RKD)
, thereby enabling other signal processing researchers
to develop their own automated moldmate identifiers.
2014 / The Dutch University Insitute for Art History
in Florence joined the CLiP project by providing access
to their collection of high resolution images of
over 1000 low-energy x-radiographs of
Rembrandt's prints from the collections of several museums
revealing the full-print chain line pattern.
2015 / Paper
original matching strategy to RKD dataset
published in a special issue on signal
processing for art investigation in the July issue of the
IEEE Signal Processing Magazine
2016 / Improved strategy combining
semi-automated chain line marking plus
optimal straight line extraction and pattern matching
applied to Dutch University Institue for Art History dataset
presented at 50th Asilomar Conference on Signals,
Systems, and Computers.
