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.

The text of a famous literary work (minus the main character) was used to generate this word cloud?  Q1. Name the author.  Q2. Name the work.

Hint 1: The word ‘reshapes’ can be name from the letters of the author’s last name.

Hint 2: The phrase ‘Hear me as I will speak,’ is an anagram of the author’s first and last name.

Hint 3: I think his mum would have called the author Bill.

Answer: Hamlet, Williams Shakespeare

There are n=3 choices. For a group of k=3 pixels, there are
n x k=9
possible combinations of colors, {RRR, RRG, RRB, RGG …}.

However if one pixel is red, we are left with k=2 and the following
n x k = 6
combinations are possible, RRR, RRG, RRB, RGG, RGB, RBB.

Therefore there is only a 1/6 chance that the group will be neutral, RGB.
