A novel no-reference metric to quantify ringing annoyance in compressed images is presented. It makes use of a recently proposed method to detect regions with perceived ringing. In this paper that method is expanded with the estimation of the visibility of ringing artifacts in the detected regions. A psychovisual experiment is carried out to validate the proposed metric. Its performance is compared to existing alternatives in literature and shows to be highly consistent with subjective data
