Perceptual Image Quality Assessment With Transformers [PDF]
2021 IEEE/CVF Conference on Computer Vision and Pattern Recognition Workshops (CVPRW), 2021 In this paper, we propose an image quality transformer (IQT) that successfully applies a transformer architecture to a perceptual full-reference image quality assessment (IQA) task. Perceptual representation becomes more important in image quality assessment.

Perceptual Quality Assessment of Pan-Sharpened Images [PDF]
Remote Sensing, 2019 Pan-sharpening (PS) is a method of fusing the spatial details of a high-resolution panchromatic (PAN) image with the spectral information of a low-resolution multi-spectral (MS) image.

Perceptual quality evaluation for motion deblurring
IET Computer Vision, 2018 Motion deblurring has been widely studied. However, the relevant quality evaluation of motion deblurred images remains an open problem. The motion deblurred images are usually contaminated by noise, ringing and residual blur (NRRB) simultaneously ...

Image Restoration Quality Assessment Based on Regional Differential Information Entropy
Entropy, 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

Attention improves perceptual quality [PDF]
Psychonomic Bulletin & Review, 2012 Attention has been demonstrated to affect response speed, signal detection, and perceptual enhancement. We wished to determine whether exogenously cued attention had the additional effect of improving the veridicality of perceptual representations. We determined the accuracy and precision of orientation judgments for static and dynamic stimuli when ...

Quality Assessment for DIBR-Synthesized Images With Local and Global Distortions
IEEE Access, 2020 Depth-Image-Based-Rendering (DIBR), as one important technique in 3D video system, can be used to generate virtual views. Unfortunately, the DIBR algorithms will introduce various distortions and induce an annoying viewing experience.

Modeling and evaluation of multimodal perceptual quality [PDF]
IEEE Signal Processing Magazine, 1997 The increasing performance requirements of multimedia modalities, carrying speech, audio, video, image, and graphics emphasize the need for assessment methods of the total quality of a multimedia system and methods for simultaneous analysis of the system components. It is important to take into account still more perceptual characteristics of the human

Perceptual quality assessment for video watermarking [PDF]
Proceedings. International Conference on Information Technology: Coding and Computing, 2005 The reliable evaluation of the performance of watermarking algorithms is difficult. An important aspect in this process is the assessment of the visibility of the watermark. We address this issue and propose a methodology for evaluating the visual quality of watermarked video.
