Abstract
In this paper, we propose a novel stereoscopic image quality assessment (SIQA) method by learning non-negative matrix factorization (NMF)-based color visual characteristics for monocular perception and considering binocular interactions. In training phase, a feature basis matrix is learned based on NMF by considering color information and a feature detector is designed by performing Schmidt orthogonalization on the feature basis matrix. In construction of SIQA phase, for monocular perception, visual saliency regions are selected and parts-based feature similarity indexes of left and right views based on the feature vectors extracted by the feature detector are calculated. For binocular interactions, we calculate cyclopean feature similarity index by considering binocular fusion and rivalry. Finally, support vector regression is used to simulate nonlinear relationship between monocular perception and binocular interactions. Experimental results on LIVE 3D image databases and NBU 3D IQA database demonstrate that the proposed SIQA method is more consistent with human perception.
