Standardization of Image Quality Analysis – ISO 19264

There are a variety of image quality analysis tools available for the archiving world, which are based on different test charts and analysis algorithms.

ISO has formed a working group in 2012 to harmonize these approaches and create a standard way of analyzing the image quality for archiving systems. This has resulted in three documents that have been or are going to be published soon. ISO 19262 defines the terms used in the area of image capture to unify the language. ISO 19263 describes the workflow issues and provides detailed information on how the measurements are done.

Last but not least ISO 19264 describes the measurements in detail and provides aims and tolerance levels for the different aspects. This paper will present the new ISO 19264 technical specification to analyze image quality based on a single capture of a multi-pattern test chart, and discuss the reasoning behind its current design.
