No-Reference Video Quality Assessment Using Codec Analysis [PDF]

open access: yesIEEE Transactions on Circuits and Systems for Video Technology, 2015
A no-reference (NR) video quality assessment (VQA) method is presented for videos distorted by H.264/Advanced Video Coding (AVC) and MPEG-2. The assessment is performed without access to the bitstream. Instead, we analyze and estimate coefficients based on decoded pixels.

Review: A Survey on Objective Evaluation of Image Sharpness

open access: yesApplied Sciences, 2023
Establishing an accurate objective evaluation metric of image sharpness is crucial for image analysis, recognition and quality measurement. In this review, we highlight recent advances in no-reference image quality assessment research, divide the ...

NoR-VDPNet++: Real-Time No-Reference Image Quality Metrics

open access: yesIEEE Access, 2023
Efficiency and efficacy are desirable properties for any evaluation metric having to do with Standard Dynamic Range (SDR) imaging or with High Dynamic Range (HDR) imaging. However, it is a daunting task to satisfy both properties simultaneously.

No-reference image quality assessment through the von Mises distribution [PDF]

open access: yes, 2012
An innovative way of calculating the von Mises distribution (VMD) of image entropy is introduced in this paper. The VMD's concentration parameter and some fitness parameter that will be later defined, have been analyzed in the experimental part for ...

Review of Research on Video Quality Assessment Based on Deep Learning

open access: yesJisuanji kexue yu tansuo, 2021
Video quality assessment (VQA) is based on the subjective quality assessment results of the human eye, using models to evaluate distorted videos. It is difficult for traditional assessment methods to make subjective assessment results consistent with ...

Perceptually-Informed No-Reference Image Harmonisation

open access: yes, 2022
Many image synthesis tasks, such as image compositing, rely on the process of image harmonisation. The goal of harmonisation is to create a plausible combination of component elements. The subjective quality of this combination is directly related to the existence of human-detectable appearance differences between these component parts, suggesting that

Spatio-temporal patterns of ovarian development and VgR gene silencing reduced fecundity in parthenogenetic Artemia

open access: yesOpen Biology, 2023
The halophilic zooplankton brine shrimp Artemia has been used as an experimental animal in multidisciplinary studies. However, the reproductive patterns and its regulatory mechanisms in Artemia remain unclear.

Automatic no-reference image quality assessment

open access: yesSpringerPlus, 2016
No-reference image quality assessment aims to predict the visual quality of distorted images without examining the original image as a reference. Most no-reference image quality metrics which have been already proposed are designed for one or a set of predefined specific distortion types and are unlikely to generalize for evaluating images degraded ...
