Genetic Diversity Analysis of Coxsackievirus A8 Circulating in China and Worldwide Reveals a Highly Divergent Genotype

open access: yesViruses, 2020
Coxsackievirus A8 (CV-A8) is one of the pathogens associated with hand, foot and mouth disease (HFMD) and herpangina (HA), occasionally leading to severe neurological disorders such as acute flaccid paralysis (AFP). Only one study aimed at CV-A8 has been

Dimensional continuation without perturbation theory [PDF]

open access: yes, 1995
A formula is proposed for continuing physical correlation functions to non-integer numbers of dimensions, expressing them as infinite weighted sums over the same correlation functions in arbitrary integer dimensions.

Image Quality Assessment Based on Multi-Scale Representation and Shifting Transformer

open access: yesIEEE Access
In automatic control systems, sensors and cameras are often used to capture images of the environment or processes being monitored. The quality of these images is paramount as it directly affects the system’s ability to accurately interpret and ...

A no-reference perceptual blockiness metric [PDF]

open access: yes2008 IEEE International Conference on Acoustics, Speech and Signal Processing, 2008
A novel no-reference blockiness metric that can automatically and perceptually quantify blocking artifacts of DCT coding is presented. The proposed metric is built upon the specific structure information of the artifact itself combined with the properties of the human visual system (HVS) by means of a simple and efficient model of visual masking ...

Deep Neural Networks for No-Reference and Full-Reference Image Quality Assessment

open access: yes, 2017
We present a deep neural network-based approach to image quality assessment (IQA). The network is trained end-to-end and comprises ten convolutional layers and five pooling layers for feature extraction, and two fully connected layers for regression ...

Fast No-reference Deep Image Dehazing

open access: yesMachine Vision and Applications
Abstract This paper presents a deep learning method for image dehazing and clarification.The main advantages of the method are high computational speed and usingupaired image data for training. The method adapts the Zero-DCE approach for the image dehazing problem and uses high-order curves to adjust the dynamicrange of images and achieve ...

Efficient No-Reference Quality Assessment and Classification Model for Contrast Distorted Images

open access: yes, 2018
In this paper, an efficient Minkowski Distance based Metric (MDM) for no-reference (NR) quality assessment of contrast distorted images is proposed. It is shown that higher orders of Minkowski distance and entropy provide accurate quality prediction for ...

Video Quality Analysis: Steps towards Unifying Full and No Reference Cases

open access: yesStandards, 2022
Video quality assessment (VQA) is now a fast-growing field, maturing in the full reference (FR) case, yet challenging in the exploding no reference (NR) case.
