No-Reference Image Quality Assessment and Application Based on Spatial Domain Coding

open access: yesIEEE Access, 2018
Aiming at the problem that a no-reference (NR) image quality assessment algorithm is not accurate enough to predict the image quality at present, we proposed a method of NR image quality assessment based on spatial domain coding (SDC).

Quality Assessment of SAR-to-Optical Image Translation

open access: yesRemote Sensing, 2020
Synthetic aperture radar (SAR) images contain severe speckle noise and weak texture, which are unsuitable for visual interpretation. Many studies have been undertaken so far toward exploring the use of SAR-to-optical image translation to obtain near ...

Image Restoration Quality Assessment Based on Regional Differential Information Entropy

open access: yesEntropy, 2023
With the development of image recovery models, especially those based on adversarial and perceptual losses, the detailed texture portions of images are being recovered more naturally. However, these restored images are similar but not identical in detail

Quality Assessment of Stereoscopic Images

open access: yesEURASIP Journal on Image and Video Processing, 2008
Several metrics have been proposed in literature to assess the perceptual quality of two-dimensional images. However, no similar effort has been devoted to quality assessment of stereoscopic images. Therefore, in this paper, we review the different issues related to 3D visualization, and we propose a quality metric for the assessment of stereopairs ...

Image Quality Assessment Using Image Description in Information Theory

open access: yesIEEE Access, 2018
In this paper, a novel image quality assessment (IQA) model using statistic features based on image information theory is proposed. Firstly, the image is decomposed into non-overlapped patches and transformed into the saliency information, specific ...

Objectively measuring signal detectability, contrast, blur and noise in medical images using channelized joint observers [PDF]

open access: yes, 2013
To improve imaging systems and image processing techniques, objective image quality assessment is essential. Model observers adopting a task-based quality assessment strategy by estimating signal detectability measures, have shown to be quite successful ...

End-to-End Image Patch Quality Assessment for Image/Video With Compression Artifacts

open access: yesIEEE Access, 2020
In this paper, we present an experimental image quality assessment (IQA) method for image/video patches with compression artifacts. Using the High Efficiency Video Coding (HEVC) standard, we create a new database of image patches with compression ...

IV-PSNR: Software for immersive video objective quality evaluation

open access: yesSoftwareX, 2023
In this article, we present the IV-PSNR software, which allows for objective quality assessment of immersive video. The software outputs the IV-PSNR metric calculated for a pair of raw video files.

On color image quality assessment using natural image statistics

open access: yes, 2014
Color distortion can introduce a significant damage in visual quality perception, however, most of existing reduced-reference quality measures are designed for grayscale images.

Influence of study design on digital pathology image quality evaluation : the need to define a clinical task [PDF]

open access: yes, 2017
Despite the current rapid advance in technologies for whole slide imaging, there is still no scientific consensus on the recommended methodology for image quality assessment of digital pathology slides.
