A psychovisual experiment on the use of Gibbs potential for the quality assessment of geometrically distorted images
Human Vision and Electronic Imaging XIII
Human perception of image distortions has been widely explored in recent years, however, research has not dealt with distortions due to geometric operations. As a consequence, there is a lack of objective visual quality measures for this class of distortions. In this paper we propose a method of objectively assessing the perceptual quality of geometrically distorted images. Our approach is based on the theory of Markov Random Fields. The idea is that the potential function of the Markov Randomdoi:10.1117/12.765879 dblp:conf/hvei/DAngeloPB08 fatcat:6kzztx4xozgu5mfzdta7o6khwe
