TLDR
A subjective experiment attempting to determine users’ preference with respect to these two types of content in two different viewing scenarios—with and without the HDR reference shows that the absence of the reference can significantly influence the subjects' preferences for the natural images, while no significant impact has been found in the case of the synthetic images.Abstract:
The popularity of high dynamic range (HDR) imaging has grown in both academic and private research sectors. Since the native visualization of HDR content still has its limitations, the importance of dynamic range compression (i.e., tone-mapping) is very high. This paper evaluates observers’ preference of experience in context of image tone-mapping. Given the different nature of natural and computer-generated content, the way observers perceive the quality of tone-mapped images can be fundamentally different. In this paper, we describe a subjective experiment attempting to determine users’ preference with respect to these two types of content in two different viewing scenarios—with and without the HDR reference. The results show that the absence of the reference can significantly influence the subjects’ preferences for the natural images, while no significant impact has been found in the case of the synthetic images. Moreover, we introduce a benchmarking framework and compare the performance of selected objective metrics. The resulting dataset and framework are made publicly available to provide a common test bed and methodology for evaluating metrics in the considered scenario.read more

A Gabor Feature-Based Quality Assessment Model for the Screen Content Images
TL;DR: Experimental simulation results obtained from two large SCI databases have shown that the proposed GFM model yields a higher consistency with the human perception on the assessment of SCIs but also requires a lower computational complexity, compared with that of classical and state-of-the-art IQA models.

MC360IQA: A Multi-channel CNN for Blind 360-Degree Image Quality Assessment
TL;DR: This paper builds a compressed VR image quality (CVIQ) database, and proposes a multi-channel convolution neural network (CNN) for blind 360-degree image quality assessment (MC360IQA), which achieves the best performance among the state-of-art full-reference and no-reference image quality Assessment (IQA) models on the CVIQ database and other available360-degree IQA database.

A perceptual framework for contrast processing of high dynamic range images
TL;DR: Inspired by gradient domain methods, this work derives a framework that imposes constraints on the entire set of contrasts in an image for a full range of spatial frequencies, so that even severe image modifications do not reverse the polarity of contrast.

A Fast Wavelet-Based Algorithm for Global and Local Image Sharpness Estimation
Phong V. Vu,Damon M. Chandler +1 more
TL;DR: Testing on several image databases demonstrates that, despite its simplicity, FISH is competitive with the currently best-performing techniques both for sharpness estimation and for no-reference image quality assessment.

Dynamic range independent image quality assessment
TL;DR: In this article, the human visual system is used to detect and classify visible changes in the image structure, and a new metric for image quality assessment is proposed based on the detection and classification of visible changes.

A perceptual framework for contrast processing of high dynamic range images
TL;DR: To predict the visibility of suprathreshold contrast, it is shown that a complex contrast compression operation, which preserves textures of small contrast, is reduced to a linear scaling in the proposed visual response space.
