Distortion-specific feature selection algorithm for universal blind image quality assessment

Abstract: Blind image quality assessment (BIQA) aims to use objective measures for predicting the quality score of distorted images without any prior information regarding the reference image. Several BIQA techniques are proposed in literature that use a two-step approach, i.e., feature extraction for distortion classification and regression for predicting the quality score. In this paper, a three-step approach is proposed that aims to improve the performance of BIQA techniques. In the first step, feature extraction is … Show more

“…Other works have also explored feature selection for BIQA [51], [52]. They analyzed each feature individually by training a model and determining its performance with different metrics such as Spearman rank correlation coefficient (SRCC), PCC, root mean square error and Kendall correlation coefficient.…”

“…Compared with conventional 2D image quality assessment (IQA), it is more challenging to evaluate the quality of stereoscopic panoramic images due to the unlimited field of view (FoV) and extra dimension of depth perception [4]. Although IQA has been researched in recent years [5]- [7], a few works have been done to predict the perceptual quality of stereo 360 images which remains an intractable research problem.…”
