Research aimed at measuring the color variation in (eye) retinal imaging was reported in a poster and article
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.

Judit Martinez Bauza, Qualcomm Inc, and I will be presenting the results of a study to develop a method for intrinsic camera resolution evaluation. This will be part of the Image Quality and System Performance Conference, http://spie.org/EI/conferencedetails/image-quality-system-performance
The measure is intended to ‘see through’ operations for which image detail is retrievable but measure the loss of image resolution otherwise. We adopt a two-stage image capture model. The first stage comprises a locally-stable point-spread function (lens), the integration and sampling by the detector (imager), and the introduction of detector noise. The second stage comprises the spatial image processing. We describe the validation of the method, which was done using both simulation and actual camera evaluations.
National Public Radio today broadcast a story about a web-based tool for organizing and searching the US Library of Congress’s large collection of depression-era (1935-46) Photographs. The collection was created by US Farm Security Administration and Office of War Information.
Photogrammar, organized by Professor Laura Wexler and a team at Yale University, provides several ways to explore the collection. Links are provided to the posted digital records, including the high-resolution digital images.

Film (Re-) Scanning: The original film scanning was performed in the 1990s, but in 2010 the Library of Congress (LC) started a project to rescan the film originals, following improvements in image capture technology. This effort is initially focusing on the most at-risk film negatives, according to Don Williams who contributes to imaging performance monitoring and standards for LC. Don (Image Science Associates) and I provide both consulting and tools to support this and other image quality assurance programs. The project is ongoing.

FADGI: The guidelines used to maintain consistent imaging performance were developed under the Federal Agencies Digitization Guidelines Initiative (FADGI), and include techniques that Don and I present in our series of courses and workshops, e.g. IS&T’s Archiving Conference. In 2015 the conference will be held at the Getty Museum in Los Angeles.
