Rapid Capture and IS&T’s Archiving Conference

by Brndan McCabeArch2015_smallSeveral articles at Smithsonian.com about rapid (image) capture reminded me of the connections to our IS&T Archiving Conference community. Briefly, Rapid Capture is used to describe high-speed image capture and storage for large digitization projects. The Rapid Capture Team* was formed with members from several cultural institutions including Ken Rahaim, Smithsonian Institution, who has been a member of the conference Program Committee. Recent examples of Rapid Capture Pilot Projects include;

  • Thomas Sears Collection at the Archives of American Gardens (photographic plates)
  • Bumblebees, from the National Museum of Natural History (45,000 bees)
  • Historical Currency (printing) Proofs, from the National Numismatic Collection housed at the Smithsonian’s National Museum of American History (250,000 items)
  • Freer Study Collection, Freer Sackler Museum
  • National Air and Space Museum

Large-scale digital collection acquisition is made practical by using automated methods for monitoring imaging performance, and custom built hardware systems for object handling. Untitled-1

Test Targets: Here Richard Kurin, Smithsonian Institution, checks out the imaging for the Historical Currency collection (Photo by Günter Waibel). The Object-level Test Target, shown expanded, is used to monitor the camera focus, lighting, color capture, etc. Such targets and associated software, are used in quality assurance programs, now part of national and international bee_squareguidelines for digitization for repositories and museums –  frequently presented at Archiving Conferences. Speaking of targets, here is the same one being used as part of the Bumblebees project – 6000 bees were captured in the first two weeks. (Photo from Smithsonian Digitization Facebook page) According to Tim Zaman this may be the Most Digitized Test Target in the WorldA bold statement, until you consider that it is designed to be captured alongside each object, and has been used in four of the five projects mentioned above, and many others in the US and Europe for several years. (more on this in another blog posting …)

Hardware: For very large projects, fully automated conveyor-belt systems are employed. Here is a frame from a video showing the operation of a system delivered and set up by Picturae BV. Olaf Slijkhuis is shown in this belt’s eye view. Olaf also presents frequently at the Archiving Conference series, most recently in Berlin 2014.olaf_aMetadata: At the Archiving Conference imaging is just one part of the program which also includes sessions on digital preservation, forensics and curation,  and metadata verification. So here is a nod to metadata. Below is an example image from the Bumblebees collection. We see the various note cards that were captured along with the insect. Presumable they all mean more or less Bombus Affinis Cresson ♂ .BombusAffinisCresson

Et Alii: The IS&T Archiving Conference is in its eleventh year and many participants have contributed to the development of the methods and tools which support rapid image capture and verification for the cultural heritage community. Although my list will be incomplete, for those interested, I suggest submitting the following terms to your favorite search engine; FADGI, Metamorfoze,  Image Engineering, Imatest, digital workflow, archiving conference … or ask via comments on this page.

Archiving 2015: Short course on Scanner and Camera Imaging

Guinea_note2a

Guinea Bank note, 1802

Don Williams and I will be presenting our new half-day course, Ten Commandments of Good Scanner & Camera Imaging Performance on 19 May, as part of IS&T’s Archiving 2015 Conference in Los Angeles. We will focus on simple and achievable tools/techniques to build a solid digital imaging foundation for museums and archives.

Our informal seminar-style course usually includes about a dozen participants, so we can discuss specific topics that come up. For example, US Federal (FADGI) and European Metamorfoze guidelines.

Since we present in the morning, those interested might consider also attending a more Arch2015_smalldetailed course on the Metamorfoze Preservation Imaging Guidelines, presented by Hans van Dormolen in the afternoon.

Imaging Performance Measurement Course at EI 2015

Untitled 3Don Williams and I will be present our  4-hour course at the Electronic Imaging Symposium in San Francisco on 10 Feb.

We use a workshop / seminar discussion format.

New this year

  • Raw image files for spatial performance measurement
  • Don Williams’ imaging Standards Rodeo discussion of recent developments
  • Intrinsic performance (reducing the influence of image processing)
  • Simple statistical methods for reducing variability (with example Matlab functions)

Retinal fundus cameras, color variation and ColorGauge targets

Research aimed at measuring the color variation in (eye) retinal imaging was reported in a poster and articleeye_color1 at the Congress of the International Academy of Digital Pathology (IADP) recently. The authors, Christye Sisson, Susan Farnand, Mark Fairchild, (Rochester Institute of Tech.), and Bill Fischer (Univ. of Rochester) proposed the use of a model eye and a small color target.

The testing confirmed wide variation in color capture among fundus camera systems. In most cases, however, the performance differences were mitigated by custom color-correction software operations.

Such corrections, e.g. implemented by custom ICC color profiles, rely on reference test charts. The authors used a miniature (0.95 cm x 1.1 cm) version of a color test chart supplied by Don Williams,  and available from Image Science Associates.
