“…Furthermore, enhancement technologies may possibly play a more significant role in future IQA research, since they are able to generate betterlooking images, even outperforming the natural images that are deemed to have the optimal quality. At the same time, further research is needed in screen content images, which are becoming particularly important due to their applications in remote computing and cloud gaming [19,14,55].…”

Quality assessment metric of stereo images considering cyclopean integration and visual saliency.Information Sciences, 373, Additional Information:• This paper was accepted for publication in the journal Informa- AbstractIn recent years, there has been great progress in the wider use of threedimensional (3D) technologies. With increasing sources of 3D content, a useful tool is needed to evaluate the perceived quality of the 3D videos/images. This paper puts forward a framework to evaluate the quality of stereoscopic images contaminated by possible symmetric or asymmetric distortions. Human visual system (HVS)studies reveal that binocular combination models and visual saliency are the two key factors for the stereoscopic image quality assessment (SIQA) metric. Therefore inspired by such findings in HVS, this paper proposes a novel saliency map in SIQA metric for the cyclopean image called "cyclopean saliency", which avoids complex calculations and produces good results in detecting saliency regions. Moreover, experimental results show that our metric significantly outperforms conventional 2D quality metrics and yields higher correlations with human subjective judg- * Corresponding author ment than the state-of-art SIQA metrics. 3D saliency performance is also compared with "cyclopean saliency" in SIQA. It is noticed that the proposed metric is applicable to both symmetric and asymmetric distortions. It can thus be concluded that the proposed SIQA metric can provide an effective evaluation tool to assess stereoscopic image quality.

“…In our NIQMC metric, we do not directly pick the salient areas for weighting, akin to the strategy adopted in many IQA approaches [2], [8], [31]- [33], because it has been presented above that the maximum-information region is required and the saliency map is merely used for assistance. Considering that if an image contains obvious foreground and background it will have comparatively centralized salient regions (i.e., the foreground) which communicate the valuable (unpredictable) information, or else salient areas may be distributed dispersedly and thus the valuable (unpredictable) information will be represented almost using the entire image.…”

The general purpose of seeing a picture is to attain information as much as possible. With it, we in this paper devise a new no-reference/blind metric for image quality assessment (IQA) of contrast distortion. For local details, we first roughly remove predicted regions in an image since unpredicted remains are of much information. We then compute entropy of particular unpredicted areas of maximum information via visual saliency. From global perspective, we compare the image histogram with the uniformly distributed histogram of maximum information via the symmetric Kullback-Leibler divergence. The proposed blind IQA method generates an overall quality estimation of a contrast-distorted image by properly combining local and global considerations. Thorough experiments on five databases/subsets demonstrate the superiority of our training-free blind technique over state-of-the-art full- and no-reference IQA methods. Furthermore, the proposed model is also applied to amend the performance of general-purpose blind quality metrics to a sizable margin.
