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

IEEE 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 ...

Machine Learning‐Based Estimation of Experimental Artifacts and Image Quality in Fluorescence Microscopy

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
The use of image quality metrics in combination with machine learning enables automatic image quality assessment for fluorescence microscopy images. The method can be integrated into the experimental pipeline for optical microscopy and utilized to classify artifacts in experimental images and to build quality rankings with a reference‐free approach ...

DrLS: Distortion‐Resistant Lossless Steganography via Colour Depth Interpolation

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT The lossless data steganography is to hide a certain amount of information into a container image. Previous lossless steganography methods fail to strike a balance between capacity, imperceptibility, accuracy, and robustness, commonly vulnerable to distortion on container images.

A No-Reference Image Quality Assessment Metric by Multiple Characteristics of Light Field Images

IEEE Access, 2019
Evaluation of light field image (LFI), especially micro-lens camera light field (LF), is a new and challenging work. The development of image quality assessment (IQA) metric of LFIs relies on the subjective quality assessment database.

Unifying Structural and Semantic Similarities for Quality Assessment of DIBR-Synthesized Views

IEEE Access, 2022
Multi-view 3D content is subject to distortions during the process of depth image-based rendering (DIBR). Studies have shown the unreliable performance of the well-established image quality assessment (IQA) models for evaluation of DIBR-synthesized views

An Examination of Task‐Evoked fMRI Data Processing in Functional Connectivity

Journal of Neuroscience Research, Volume 104, Issue 6, June 2026.
In this work, we analyzed the preprocessing of task‐fMRI data to explore the contribution of the task information in connectomics towards a methodological consensus for preprocessing among task‐state connectivity studies. We investigated whether a task‐free connectivity can be inferred from task‐fMRI and examined its impact upon a clinical disorder ...

Collective Interactions in Ion Pairs

Journal of Computational Chemistry, Volume 47, Issue 14, 30 May 2026.
This study demonstrates, by means of the analysis of the electron density topology, that collective interactions stabilize ion pairs through the simultaneous engagement of multiple atoms, rather than simple pairwise electrostatics. ABSTRACT Collective interactions represent a recently proposed bonding mode in which stabilization arises not from a ...

On the optimization of the geometric pattern for structured illumination based X‐ray phase contrast and dark‐field imaging: a simulation study and its experimental validation

Journal of Synchrotron Radiation, Volume 33, Issue 3, Page 806-817, May 2026.
Single‐mask phase contrast and dark‐field imaging methods offer the great advantage of being simple to implement, translating most of the complexity to the numerical side. In this work, we study the impact of the modulation topology on the image quality retrieved both on numerical simulation and experiments.Phase contrast and dark‐field imaging are ...

SEM Image Quality Assessment Based on Intuitive Morphology and Deep Semantic Features

IEEE Access, 2022
The widespread use of scanning electron microscopy (SEM) has increased the requirements for SEM image quality. SEM images obtained by electron beam feedback have more complex texture features than natural images obtained by optical imaging, and this ...
