Edge-region information measure based on deformed and displaced pixel for image quality assessment / Zianou Ahmed Seghir in Signal processing. Image communication, Vol. 26 N° 8-9 (Octobre 2011)

Image communication > Vol. 26 N° 8-9 (Octobre 2011) . - pp. 534–549 Titre : Edge-region information measure based on deformed and displaced pixel for image quality assessment Type de document : texte imprimé Auteurs : Zianou Ahmed Seghir, Auteur ; Fella Hachouf, Auteur Année de publication : 2012 Article en page(s) : pp. 534–549 Note générale : Electronique Langues : Anglais (eng) Mots-clés : IQA  Difference  mean  opinion  score  (DMOS)  Displaced  pixel  Distorted  pixel Résumé : Image quality depends on many factors, such as the initial capture system and its image processing, compression, transmission, the output device, media and associated viewing conditions. The goal of quality assessment research is to design measures that can automatically evaluate the quality of images in a perceptually consistent manner. This paper proposes a new measure for image quality assessment (IQA), which supplies more flexibility than previous methods in using the pixel displacement in the assessment. First, the distorted and original images are divided into overlapped 11×11 blocks, and secondly, we calculated distorted pixels and displacement, and then, visual regions of interest and edge information are computed, which can be used to compute the global error. Experimental comparisons show the efficiency of the proposed method.
