La reconstruction d'images en super résolution (SR) a attiré une attention croissante ces années-ci et de nombreux algorithmes de reconstruction d'images SR ont été proposés pour restaurer une image haute résolution à partir d'une ou plusieurs images basse résolution. Cependant, comment évaluer objectivement la qualité des images reconstruites SR reste un problème ouvert. Bien qu’un grand nombre de mesures de qualité d’image aient été proposées, elles sont assez limitées pour évaluer la qualité des images reconstruites SR. Inspiré par cela, cet article présente un indice de qualité aveugle pour les images reconstruites SR utilisant une dégradation structurelle du premier et du deuxième ordre. Tout d’abord, l’image reconstruite SR est décomposée en cartes de magnitude dérivée multi-ordres, efficaces pour la représentation structurelle du premier et du deuxième ordre. Ensuite, des caractéristiques basées sur l'énergie logarithmique sont extraites sur ces cartes de magnitude dérivée multi-ordres dans le domaine fréquentiel. Enfin, la régression vectorielle de support est utilisée pour apprendre le modèle de qualité des images reconstruites SR. Les résultats d'expériences approfondies menées sur une base de données publique démontrent les performances supérieures de la méthode proposée par rapport aux mesures de qualité existantes. De plus, la méthode proposée dépend moins du nombre d’images d’entraînement et présente un faible coût de calcul.

Abstract: Super resolution (SR) image reconstruction has attracted increasing attention these years and many SR image reconstruction algorithms have been proposed for restoring a high-resolution image from one or multiple low-resolution images. However, how to objectively evaluate the quality of SR reconstructed images remains an open problem. Although a great number of image quality metrics have been proposed, they are quite limited to evaluate the quality of SR reconstructed images. Inspired by this, this paper presents a blind quality index for SR reconstructed images using first- and second-order structural degradation. First, the SR reconstructed image is decomposed into multi-order derivative magnitude maps, which are effective for first- and second-order structural representation. Then, log-energy based features are extracted on these multi-order derivative magnitude maps in the frequency domain. Finally, support vector regression is used to learn the quality model for SR reconstructed images. The results of extensive experiments that were conducted on one public database demonstrate the superior performance of the proposed method over the existing quality metrics. Moreover, the proposed method is less dependent on the number of training images and has low computational cost.
