Image Quality Experience

Many users accept the emerging methods for measuring and assessing digital image quality. However, they are reluctant to adopt them because they haven’t the experience, confidence, or time and resources to adequately ensure a useful outcome. Still others are required to adopt these methods, but remain uncertain about how to interpret the results.

We bring more than a decade of experience in cultural heritage image quality and have a large imaging performance database for device comparisons, qualifying us to be independent guardians of your financial investment.

Scanner/Camera Acceptance Testing

Before you sign off on that expensive and complex scanning device, be sure that it is performing as expected. We work with you to create a comprehensive acceptance test plan and evaluation process, that we perform, to ensure your image quality expectations are met. We act on your behalf with your vendor to achieve a mutual and economic delivery agreement. We get involved.

Periodic Image Quality Monitoring and Audits

Using a Image Science Associates Target at the Smithsonian

Any number of imaging inconsistencies can creep unnoticed into your digitizing workflows, or those of your service provider. From incorrect exposure selections to inappropriate image processing choices, we know how these changes manifest themselves in image quality metrics. When used with the GoldenThread imaging tools, we can design an image quality program for you that will allow us to track, report, and in many cases diagnose and fix such behaviors for a more consistent imaging product. We do more than measurements; we find solutions for your imaging challenges.

Image Quality Specifications

Given the wide range of materials to be imaged and the many possible use cases of digitized images, it is a daunting task to determine just how the scan specifications should be constructed. Let us help you bring our experience to your project by:

  • Creating air-tight job requirements for more accurate, cost-effective quoting
  • Setting up conformance testing to ensure specifications are met
  • Installing quality control protocols on your production floor

The Check is in the Manager's Hand

A regional public library in Northwest Ohio hired ISA to perform on-site scanner acceptance testing for a newly installed A0 scanner. Before payment was to be made to the scanner’s vendor it was required to pass FADGI 3-Star performance. After four hours of anguished tweaking it was still far from that goal. The manager refused to cut the check until the required FADGI specs were met. The scanner’s manufacturer made firmware and calibration procedure changes over the following month. Through dropbox and desktop sharing, ISA confirmed that the changes made led to the required FADGI required levels. Payment was then made.


Scanner Win-Win

ISA’s GoldenThread targets and software helped identify several image quality shortcomings on a newly installed 2A0 scanner ($$$) at the world’s largest library. The specificity of the software’s image quality report allowed the customer to make detailed improvement suggestions to the vendor on the scanner’s hardware and software. The vendor happily complied. This was a win-win. The library got the image quality they paid for and expected and, because the image quality was greatly improved the library purchased another scanner. Customer wins. Vendor wins.
