Abstract

A novel approach towards automatic detection of perceived ringing regions is presented. The algorithm takes into account both the physical structure and the human visual perception of the ringing artifacts. All perceived ringing regions are explicitly captured by means of a newly proposed edge detector, followed by an efficient analysis of ringing visibility around each detected edge segment. Determining visibility is based on luminance masking and texture masking as typical for the human visual system. The proposed detection method is validated by comparing its performance with the ringing regions resulting from a psychovisual experiment.
