Error-parameter analysis based blind identification and super-resolution restoration algorithm

Tongxin xuebao, 2009
A new implementation scheme of regularization super-resolution restoration algorithm was addressed, which could remove spatial integration performed by the sensors in down-sampling process and restrain edge artifact caused by zero-padding up-sampling ...

Exploiting Thermal Self-Similarity for Robust Blind Super-Resolution of Real-World Infrared Images

IEEE Access
Infrared image super-resolution (IISR) is challenging because real infrared (IR) sensors introduce composite degradations. Optical blur couples with Gaussian noise, fixed-pattern stripe noise, and low-frequency non-uniformity, and their composition and ...

Bridging Horizontal to Vertical Radiative Cooling

Advanced Science, EarlyView.
Radiative cooling materials are mature but only work facing the sky, confining them to rooftops. Instead of developing new ones, this system bridges existing horizontal coolers to vertical windows using blades outside the glass. On an occupied urban building, windows stay up to 1.4°C below air temperature while preserving daylight, outward views, and ...

Global Prior-Guided Distortion Representation Learning Network for Remote Sensing Image Blind Super-Resolution

Remote Sensing
Most existing deep learning-based super-resolution (SR) methods for remote sensing images rely on predefined degradation assumptions (e.g., bicubic downsampling).

Arrayed Magnetic Accelerator Synergistically Enhances Orthodontic Tooth Movement via Microtubule Assembly‐Mediated Periodontal Remodeling

Advanced Science, EarlyView.
Mechanical orthodontic treatment for malocclusion is limited by slow remodeling and risks due to poor biomechanical sensing. This study shows that static magnetic fields (SMFs) enhance mechanical sensation in periodontal ligament cells, promoting inflammation and osteoclast activity.

A Novel Blind Restoration Method for Miner Face Images Based on Improved GFP-GAN Model

IEEE Access
Miner face images, as important carriers of information transmission, are an important means of digital transformation and intelligent management of mining enterprises. In order to address the issue of complex degradation factors such as noise, blurring,

Tau Aggregate Imaging and Transcriptomics of Alzheimer's Disease Brain at Different Stages of Disease

Advanced Science, EarlyView.
The protein aggregates and gene expression in the middle temporal gyrus (MTG) and somatosensory cortex (SOM) of the postmortem brains of 13 Alzheimer's disease patients were studied in detail, revealing that small hyperphosphorylated tau aggregates increase with Braak stage driven by microglial inflammation.

Enteric ChAT‐Expressing Neurons Mediate the Protective Effect of Lactobacillus plantarum in Inflammatory Bowel Disease

Advanced Science, EarlyView.
In colitis patients and mice, reduced Lactobacillus abundance is observed. Experimental studies show that L. plantarum A736 metabolizes dietary tryptophan into indole‐3‐lactic acid (ILA), while both L. plantarum A736 and ILA impact ChAT‐expressing enteric neurons and acetylcholine levels, thereby regulating intestinal immune responses and alleviating ...

Object detection with dynamic high-/low-frequency knowledge distillation for real-world degradation

Alexandria Engineering Journal
Object detection in complex degraded scenarios poses a significant challenge in real-world applications, primarily due to the loss of high-frequency information caused by image degradation, which hinders spatial localization and texture feature capture ...

Suppressing Uncertainties in Degradation Estimation for Blind Super-Resolution

Proceedings of the 32nd ACM International Conference on Multimedia
The problem of blind image super-resolution aims to recover high-resolution (HR) images from low-resolution (LR) images with unknown degradation modes. Most existing methods model the image degradation process using blur kernels. However, this explicit modeling approach struggles to cover the complex and varied degradation processes encountered in the ...
