WAKEFIELD, Mass., USA – Jan. 9, 2012 – The International Imaging Industry Association (I3A, the leading global association for the imaging industry; http://www.i3a.org) announced today that two papers arising from its Camera Phone Image Quality Initiative (CPIQ) will be delivered by CPIQ participants at the IS&T/SPIE Electronic Imaging 2012 conference, to be held in Burlingame, California, January 22-26.  Both sessions will take place on January 24.

I3A's CPIQ Initiative has been working to develop a standardized means of measuring and communicating image quality by producing a complete set of image quality testing metrics and methodologies, enabling a consumer-oriented image quality rating system.  The rating system will provide a tool for translating and distilling the complex set of measurements into a rating that consumers can quickly and easily understand, to aid in selection of camera phones.

CPIQ's work to date has been broadly influential in the scientific and standards communities and has yielded a number of published papers during the last several years.  The CPIQ group will hold a meeting for its participants before the start of the Electronic Imaging conference; for more information about joining the Initiative and attending this meeting, contact Donna Cohn, donnac@i3a.org.

"Development of the I3A CPIQ spatial metrics," presented by Henrik Eliasson of Sony Ericsson Mobile Communications AB and co-authored by Donald Baxter of STMicroelectronics Ltd., Frédéric Cao of DxO Labs and Jonathan Phillips of the Eastman Kodak Company, describes the development of a specific group of spatial measurements within the CPIQ set of subjectively correlated image quality metrics.. Contained in this group are the edge acutance, visual noise and texture acutance metrics, which are all dependent on the spatial content of the specific scene being analyzed.

"Calibration and adaptation of ISO visual noise for camera phone image quality assessment," presented by Donald Baxter and co-authored by Andrew Murray of STMicroelectronics, describes the motivation behind the choice of a visual noise metric, why the characteristics of cell phone cameras necessitate adaptation of an ISO visual noise protocol, and the specific calibration of the adapted visual noise metric.

"These two papers are the latest examples of the significant contribution made by I3A's CPIQ initiative to furthering the scope of image quality assessment, particularly in the area of subjective analysis," said I3A President Lisa Walker.  "The breadth and depth of CPIQ papers' topics and their presentation in prestigious venues such as the Electronic Imaging conference demonstrate the initiative's high level of scientific achievement.  We are pleased to see these important papers presented to the public, and we will welcome additional CPIQ participants who share our commitment to image quality research to join our efforts."

Published research by CPIQ experts includes:

• "Camera motion and mobile imaging"
• "Image quality quantification in camera phone applications"
• "Softcopy quality ruler method: Implementation and validation"
• "Correlating objective and subjective evaluation of texture appearance with applications to camera phone imaging"
• "Interaction of image noise, spatial resolution, and low contrast fine detail preservation in digital image"
• "Slider-adjusted softcopy ruler for calibrated image quality assessment"
• "Measuring texture sharpness of a digital camera"
• "Applying image quality in cell phone cameras: lens distortion"
• "Validating a texture metric for camera phone images using a texture-based softcopy attribute ruler"
• "Dead leaves model for measuring texture quality on a digital camera"
• "Texture-based measurement of spatial frequency response using the dead leaves target: extensions, and application to real camera systems"
• "Toward a quantitative visual noise evaluation of sensors and image processing pipes"
