Reflexive Citation: Taking your published work seriously

While attending recent imaging conference, a friend told me about a recent website posting on a topic familiar to me. We had previously discussed some of the normal levels of permission needed for posting by this US government cultural institution, so it was good to see. The posted information included software and links to supporting documents, including a paper presented at a conference I had attended.

I checked the links to the software file, manual and conference paper which reported on the method used. All links intact – good so far. However, when I viewed the posted version of the published conference paper something important was missing, the original publication, date, etc. Later, checking on other posted conference papers, I found several more examples.

Background: Many conferences* publish books, e.g. Proceedings of Annual River Wideners Conf. 1972. These proceedings books are published and copyrighted by the organizing society or group. In some cases, the authors are allowed to post their conference articles on their own websites. I am only addressing such permitted posting.

Posting: Back to the example I was looking at. The institution’s webpage had a link to the posted article (a PDF File). The hypertext was the article’s title only. The version of the posted article, however, had no indication of where or when it had been presented or published – reducing the chance that others would cite it in their publications.

Citation is attribution, even if it is your own work

Suggestion to Authors: masthead, nameplate or footer

Newspapers (please …) normally have a header that tells the reader the publication they are reading. This is often called the nameplate. Academic journals also have this in either a page header or footer, with page number etc.

Include reflexive citation: So if you are posting your published contributions online, increase the chance for others to read and cite your work by adding a reflexive citation in the header or footer. You probably uploaded a version for the proceedings book that did not have this information because pagination and such is done when assembling the book. Just add the citation to your version – you have the original (word processor) file.

There is probably another term for this. I am reminded of those reflexive verbs and pronouns we learnt when studying foreign languages (e.g., I feed myself /Je me nourris, I see myself / Yo me veo, or is it just, me veo) that we were unaware of in our native tongue. But we can teach ourselves no?

File under: RefCit
* While I am generally not in favour of including gratuitous pictures of AE in social media, this one seems appropriate, being from a famous conference on physics in 1927. Authors from this conference did not post their papers on-line, so did not need to add a reflexive citation.

EI02: Introduction to Image Quality Testing: Targets, Software, and Standards

EI02: Introduction to Image Quality Testing: Targets, Software, and Standards

Short Course at IS&T’s Electronic Imaging Symposium, San Francisco 29 Jan. 2017

Instructors: Peter Burns, Burns Digital Imaging, and Don Williams, Image Science Associates
8:00 – 10:00 AM (2 hours)
Course Level: Introductory
Fee: Member fee*: $165 / Non-member fee: $195 / Student fee: $60 *(after January 9, 2017 prices for all courses increase by $50, $25 for students). To register for symposium and/or short course. Early registration date, 9 Jan. 2017.

An introduction to  imaging performance evaluation for image capture, providing a foundation for more advanced topics, e.g., system characterization and performance benchmarking. We adopt a scenario-based approach by describing several situations where imaging performance needs evaluation. Each of these, from design to quality assurance for manufacturing, is addressed in terms of suggested methods, color test charts, and standard reporting. For several important attributes, we describe international standards, guidelines, and current best practice. Examples are drawn from various applications, including consumer, museum, mobile, and clinical imaging. We will help participants to;

  • Understand the difference between imaging performance and image quality.
  • Describe performance standards, guidelines, and current best practices.
  • Understand how color-encoding, image resolution, distortion, and noise are evaluated.
  • Compare various commercial analysis software products and (color, resolution) test charts.
  • Select evaluation methods and test targets to meet your project needs.
  • Identify sources of system variability and understand measurement error.

Intended Audience: This course is intended for a wide audience: image scientists, quality engineers, and others evaluating digital camera and scanner performance. No background in imaging performance (optical distortion, color-error, MTF, etc.) evaluation will be assumed.

Instructors:  Peter Burns is a consultant working in imaging system evaluation, modeling, and image processing. Don Williams is founder of Image Science Associates. Both are frequent presenters at technical imaging conferences.

Electronic Imaging Symposium 2017: Invitation


I&T’s Electronic Imaging Symposium 2017 will be held 29 January – 2 February, 2017 near San Francisco, and is now accepting submissions to present and publish your work. There are many conferences within this symposium covering a wide range of topics. The submission deadline is 4 July 2016.

The invitation to participate in the Image Quality and System Performance Conference (IQSP) is here.

As you will see, suggested topics include three general areas

  • Image quality objective and subjective evaluation
  • Performance measurement and modeling
  • Standards for image quality and system performance

Joint sessions with IQSP are planned for three other conferences,

Citizens, not subjects: Jefferson, France* and expired passports

I recently chaired an IS&T Archiving 2016 conference session on Advanced Imaging Techniques. My role included introducing Fanella France, US Library of Congress, presenting Spectral Imaging for Preservation Documentation. An example cited was the discovery that in the US Declaration of Independence Thomas Jefferson had originally used the word subjects, but changed this to citizens. The interpretation being that Americans would not be subjects of the crown, but a people (citizens) whose allegiance was to one another.

Later that morning, I mentioned this and suggested that perhaps conference attendees from Commonwealth** countries might like to check which they are considered. I intended this as a light-hearted comment, the type that session chairs make as people shuffle back from a coffee break. Conference proceeds – considered successful – splendid time had at NARA. Little did I know … 

Your papers, please …

A few of days after the conference, visiting my parents, while looking in a sock drawer, I discovered several expired family passports for my mother and her father. Having looked at the stamped visas and the passport holder information (expected, but still interesting), I happened to notice the front covers. Curious that my maternal grandfather’s 1961 Australian passport had the title; British Passport, and below the crest, Australia. Mum’s more recent 1979 passport simply said Australia Passport. Both also had the royal crown insignia, but a 1985 version did not. What’s all this?


Expired passport for Fred, aka Pa, issued in 1961

After a simple search one learns that in 1967, the word British Passport was removed from Australian passports, but the Crown was kept. The word Australia appeared below the Crown, followed by the Australian Coat of Arms and the word Passport. The crown was removed in 1984.

I learned a few things from Archiving 2016 that I had not anticipated, but that is part of the fun, isn’t it?

p.s. I found some UK ration books and a travel journal, but these stories are for another time.


*With apologies to Dr. Fanella France –  I could not resist since Mr. Jefferson was United States Minister to France (which most of you reading this far will  already know)

Ten Years After: Every Story Tells a Picture

Although it might seem simple today, ten years ago adding your own pictures to an on-line advertisement was novel. Then a Kodak employee, I noticed the following on the company web site,

Using an exclusive, free online tool, visitors to can import up to five of their digital pictures into Kodak’s Gallery commercial, then view their own “edit” of the 60-second spot. You may then share the commercial with any number of e-mail recipients. Your personalized Gallery commercial – complete with music, scenes, and dialogue from the original TV commercial – will remain viewable via the email link for a minimum of 30 days.

Kodak Gallery had me at freemy own pictures, publicly viewable. I tried it, and figured out how to download the resulting video file – not easy because that was not Kodak’s intent.

Well, I added a few images of imaging test charts that Don Williams and I were starting to use at library and archiving institutions. I sent the file to a couple of friends.IMG_2676

Fast forward to 2016. I recently stumbled on a reference to Kodak commercials and found a version of the original on YouTube. I have approximated my original effort by editing the version that I used in 2006. In fact I have done more (title, credits, etc.) – all with free software, as before. I include a few ‘nuggets’ at the end. The video quality is, of course, limited by the version posted, but it should look OK on a small screen.

From the Kodak press release, ten years ago last Monday.

ROCHESTER, N.Y.–April 3, 2006–Now, you can be in pictures. Kodak invites you to join the millions of TV viewers who were captivated last year by an emotion-filled commercial in which countless photos were preserved and shared in an infinite “Kodak Gallery.”

Surface and Texture for Museums and Galleries: Archiving 2016

imaging.org_conf_archiving2016IS&T’s Archiving Conference, 19-22 April 2016
National Archives, Washington DC

Surface and texture information is important for the study of many types of historical material. When combined with image capture, three-dimensional visualization can reveal hidden characteristics, and Archiving 2016 will provide opportunities to learn about two methods, used in museums and galleries.


Rendering using studio lights at 45° from the left and right

Four-Light Imaging (4LI) uses polarized light sources to capture information about the microstructure (impasto) of artwork. The full (multi-) spectral nature of the surface reflectance is measured, which allows computer ‘re-lighting’ for different illumination and viewing conditions. Eight images are collected for a given object, and automated software displays diffuse color and surface-normal images.

Prof. Roy Berns, Rochester Institute of Technology, will be offering his Four-Light Imaging short course.


From Cuneiform Digital Library Initiative

Reflectance Transformation Imaging (RTI) uses up to 50 still images while moving the light source. The resulting data are displayed using interactive software that simulates viewing the object at different angles as you might if holding it. The method has been applied to a range projects, including early photographs at The Smithsonian, Diego Rivera murals in San Francisco and ancient tablets at The Louvre.

Carla Schroer and Mark Mudge, Cultural Heritage Imaging, will be presenting the short course, Computational Photography Techniques for Cultural Heritage Documentation and Archiving.

Spectral Imaging: An additional, short course that complements these is to be presented by Fanella France and Meghan Wilson, Library of Congress, Spectral Imaging – Capture and Processing. In a previous post I described the planned sessions on multi-spectra imaging at the conference.
