Absolute Category Rating

Absolute Category Rating

Absolute Category Rating (ACR) is a test method used in quality tests. It has been standardized in ITU-T Recommendation P.910. [ [http://www.itu.int/rec/T-REC-P.910/en P.910 : Subjective video quality assessment methods for multimedia applications] . "ITU-T Recommendation", approved in 1999-09. Retrieved on 2008-05-29.] In this method, a single test condition (generally an image or a video sequence) is presented to the viewers once only. They should then give a quality rating on an ACR scale. Test conditions should be presented in random order.
