Papers address standard means of measuring image quality

The International Imaging Industry Association(I3A;Wakefield, MA, USA) has announced that two papers arising from its Camera Phone Image Quality Initiative (CPIQ) were presented at the IS&T/SPIE Electronic Imaging 2012 conference in Burlingame, CA this week.

The International Imaging Industry Association (I3A;Wakefield, MA, USA) has announced that two papers arising from its Camera Phone Image Quality Initiative (CPIQ) were presented at the IS&T/SPIE Electronic Imaging 2012 conference in Burlingame, CA this week.

I3A's CPIQ Initiative has been working to develop a standard means of measuring and communicating image quality by producing a complete set of image quality testing metrics and methodologies to create an 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 easily understand to aid them in the selection of camera phones.

The first of the papers -- "Development of the I3A CPIQ spatial metrics" -- was presented by Henrik Eliasson of Sony Ericsson Mobile Communications and co-authored by Donald Baxter of STMicroelectronics, Frédéric Cao of DxO Labs, and Jonathan Phillips of the Eastman Kodak Company. The second of the two -- "Calibration and adaptation of ISO visual noise for camera phone image quality assessment" -- was presented by Donald Baxter and co-authored by Andrew Murray of STMicroelectronics.

"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.
