Uniform In‐Plane Growth of Large‐Area Ultrathin Zn2(benzimidazole)4 Membrane

open access: yesAdvanced Functional Materials, EarlyView.
A multicycle, ultradilute exposure strategy enables uniform in‐plane growth of ultrathin Zn2(benzimidazole)4 membranes on graphene, suppressing bulk nucleation and defects. The resulting centimeter‐scale films deliver high H2/CO2 separation performance, and are highly reproducible.

ANALYSIS AND PREDICTION OF FILTERING EFFICIENCY USING NO-REFERENCE IMAGE VISUAL QUALITY METRICS

open access: yesРадіоелектронні і комп'ютерні системи, 2018
Images are subject to noise during acquisition, transmission and processing. Image denoising is highly desirable, not only to provide better visual quality, but also to improve performance of the subsequent operations such as compression, segmentation ...

A Second-Order Method for Removing Mixed Noise from Remote Sensing Images

open access: yesSensors, 2023
Remote sensing image denoising is of great significance for the subsequent use and research of images. Gaussian noise and salt-and-pepper noise are prevalent noises in images.

Image Denoising

open access: yes, 2006
The paper is concerned with the problem of image denoising for the case of grey-scale images. Such images consist of a finite number of regions with smooth boundaries and the image value is assumed piecewise constant within each region. New method of image denoising is proposed which is adaptive (assumption free) to the number of regions and smoothness

Wavelet Bayesian Network Image Denoising [PDF]

open access: yesIEEE Transactions on Image Processing, 2013
From the perspective of the Bayesian approach, the denoising problem is essentially a prior probability modeling and estimation task. In this paper, we propose an approach that exploits a hidden Bayesian network, constructed from wavelet coefficients, to model the prior probability of the original image.

A Synovium‐on‐Chip Platform to Study Multicellular Interactions in Arthritis

open access: yesAdvanced Healthcare Materials, EarlyView.
The Synovium‐on‐Chip comprises a thin microporous PDMS membrane to support co‐culture of fibroblast‐like synoviocytes (FLS), THP‐1‐derived macrophages, and endothelial cells, enabling real‐time analysis of synovial‐vascular interactions. FLS migration through the pores drives endothelial remodeling, while TNF‐α stimulation induces robust inflammatory ...

Multi-task learning with self-learning weight for image denoising

open access: yesJournal of Engineering and Applied Science
Background Image denoising technology removes noise from the corrupted image by utilizing different features between image and noise. Convolutional neural network (CNN)-based algorithms have been the concern of the recent progress on diverse image ...

A New Nonlinear Diffusion Equation Model for Noisy Image Segmentation

open access: yesAdvances in Mathematical Physics, 2016
Image segmentation and image denoising are two important and fundamental topics in the field of image processing. Geometric active contour model based on level set method can deal with the problem of image segmentation, but it does not consider the ...

Blockwise SURE Shrinkage for Non-Local Means

open access: yes, 2013
In this letter, we investigate the shrinkage problem for the non-local means (NLM) image denoising. In particular, we derive the closed-form of the optimal blockwise shrinkage for NLM that minimizes the Stein's unbiased risk estimator (SURE).
